Introduction
The FX-850 and FX-1050 printers combine all the well-known features of
previous Epson® 9-pin printers with many features normally exclusive to
costly 24-pin printers.
Features
In addition to the high-quality printing and ease of operation you’ve
come to expect from Epson printers, the FX-850 and FX-1050 offer the
following:
An advanced paper handling system that lets you use single sheets of
paper without removing the continuous paper. This system allows
you to use continuous paper even while the optional cut sheet feeder
is attached.
A new short tear-off feature that saves paper. After you tear off the
last sheet printed on continuous paper, the printer reverses the paper
so that you can use all of the next sheet.
A micro-adjustment feature that allows you to feed the paper
forward or backward to finely adjust the loading and short tear-off
positions.
An improved control panel design that allows direct selection of
character fonts and pitch, as well as a choice of draft or near letter
quality (NLQ) printing.
Draft mode with fast printing of up to 264 characters per second at
12 cpi.
The ability to handle a wide range of paper types, including
envelopes.
Double-high and double-wide printing for headings and special
emphasis.
Introduction
1
options
A variety of printer options are available for use with FX printers. For
detailed information on the installation and use of these options, see
Chapter 7.

this position later, depending on the margin settings of your
application program.)
4. Adjust the right edge guide to fit the size of the paper.
5. Slide the paper down between the edge guides until it meets
resistance. At this point, the PAPER OUT light turns off.
6. Press the LOAD/EJECT button to automatically feed the paper to the
loading position.
WARNING: Never advance the paper using the platen knob
while the printer is turned on.
7. Press the ON LINE button so that the ON LINE indicator lights up.
Paper Handling

If the platen (black roller) turns but the sheet does not load, remove the
sheet completely from the printer. Then make sure the paper release lever
is pushed back. Press the paper a bit more firmly into place and try
again.
To eject the paper, press the ON LINE button to take the printer off line,
and press the LOAD/EJECT button.
Reloading during printing
When you print a document more than one page long using single sheet
paper, the printer stops printing when it reaches the bottom of the paper
and ejects the page. When this happens, either the ON LINE light goes off
automatically or it may remain on, depending on your application
software. If the ON LINE light remains on, the first thing you should do is
press the ON LINE button to take the printer off line. Once the ON LINE
light is off, remove the sheet that has just been printed and load a new
sheet as before. Press ON LINE to start printing the next page.
Using Continuous Paper
The tractor built into the FX is remarkably easy to load and operate. Its
low-profile design takes up little space and can handle a wide variety of
paper widths.
To load continuous paper, follow these steps:
1. Turn off the printer.
2. Pull the paper release lever forward to the continuous paper position.

10. Reattach the paper guide as shown below.
Paper Handling
2-7
Caution: When using continuous paper, always make sure that the
edge guides are pushed together.
11. Close the printer cover and turn on the printer.
12. Press the LOAD/EJECT button to feed the paper to the loading
position. The printer remembers this position and advances each
page to the same position.
13. Press the ON LINE button to put the printer on line so that it can
accept data.
If you find that your word processing or other application program
prints too high or too low on the page or is printing on the perforations,
check the loading position. If you need to adjust this position, you can
use the micro-adjustment feature. This feature gives you precise control
over the position of your paper by allowing you to feed the paper
forward or backward in 2/216-inch increments. For more information,
see the section on micro-adjustment later in this chapter.
When using continuous paper, you can also choose the short tear-off
feature to give you added paper handling capabilities. This feature
automatically feeds the paper forward so that you can tear it off at its
perforation. The printer then reverses the paper feed so you can resume
printing at the loading position. Short tear-off makes it easier to detach
printed pages and saves the blank pages that are usually lost between
printing jobs. See the section on short tear-off later in this chapter for
details.
WARNING: If you need to adjust the loading position,
always use the micro-adjustment feature. Never advance the
paper using the platen knob while the printer is turned on.
2-8
Paper Handling
Positioning your continuous paper supply
Three common ways of positioning your printer and continuous paper
supply are shown below.
It’s important to keep your paper supply aligned with the tractor so that
the paper feeds smoothly into the printer.
Paper Handling
2-9
Switching Between Continuous and Single Sheets
Even with continuous paper loaded in the printer, you can easily switch
to single sheet printing without removing the continuous paper from the
tractor. To switch from continuous paper to single sheets, follow the
steps below.
1. Open the printer cover and press the ON LINE button to take the
printer off line.
2. Remove your printed document. If you are not using the short tearoff function, press the FORM FEED button to advance your document
to a point where it can be removed.
Note: To avoid feeding your continuous paper backward more than is
necessary, always make sure that you tear off the printed document
before removing paper with the LOAD/EJECT button.
2-10
Paper Handling
3.
Press the LOAD/EJECT button to feed the continuous paper backward
out of the printer and into a standby position. The paper is still
attached to the tractor, but is no longer in the paper path. The
PAPER OUT light comes on when the paper is completely out of the
paper path.
Note: Pressing the LOAD/EJECT button once may not feed the paper
back enough to reach a standby position. If the PAPER OUT light does
not come on, press the LDAD/EJECT button again. With normal
continuous paper, you can press the LOAD/EJECT button up to three
times. (With continuous paper narrower than six inches, you can press
the LOAD/EJECT button only once.)
4. Push the paper release lever back to the single sheet position.

1. Open the printer cover. Lower the paper guide onto the back of the
printer.
2. Pull the paper release lever forward to the continuous paper position.
3. Press the LOAD/EJECT button to feed the paper to the loading
position.
4. Press the ON LINE button to put the printer on line.
Paper Handling
2-13
Adjusting the Loading Position
The loading position is the position of the paper when it has been
automatically loaded by the printer. This position is important because it
determines where the printing begins on the page. If the printing is too
high or too low on the page, you need to change the loading position
using the micro-adjustment feature described in the next section.
Until the loading position is reset, the printer remembers the position and
uses it as a reference point for feeding the paper.
WARNING: If you need to adjust the loading position,
always use the micro-adjustment feature. Never use the
platen knob for paper feeding except in case of a paper
feeding problem.
Once you have used micro-adjustment to change the loading position of
continuous paper, the printer remembers that position even after it is
turned off. However, when you use micro-adjustment to change the
loading position of single sheet paper, the printer does not remember this
position after the power is turned off. When the power is turned back
on, the loading position returns to its factory setting.
Using Micro-Adjustment
The micro-adjustment feature moves the paper 2/216th of an inch at a
time to make fine adjustments to the loading or short tear-off positions.
Micro-adjustment only works immediately after you load paper or use
the short tear-off function. You can use micro-adjustment only when the
printer is on line and the ON LINE indicator light is flashing.
After you adjust the tear-off position or after you adjust the loading
position for continuous paper, the printer remembers that position even
after it is turned off, reset, or initialized. However, when you adjust the
loading position for single-sheet paper, the printer does not remember the
new position after the power is tuned off.
2-14
Paper Handling
This section describes using micro-adjustment to change the loading
position, but you can adjust the short tear-off position the same way. See
the next section on using short tear-off for more information.
To perform micro-adjustment of the loading position, first load your
paper, and then press the ON LINE button to put the printer on line. The
ON LINE indicator light starts to flash. While this light is flashing, you can
use the FORM FEED and LINE FEED buttons for micro-adjustment.
Press the FORM FEED button to feed the paper forward or the LINE FEED
button to feed the paper backward.
Each time you press the button, the paper moves 2/216 of an inch. If
you hold the button down, the paper moves continuously in 2/216-inch
increments.
When the paper reaches the factory-set loading position, the printer
beeps and micro-adjustment feeding pauses for a moment before
continuing. You can use this factory setting as a reference point when
adjusting the printer’s loading position. When the paper reaches either
the minimum or maximum top margin, the printer beeps and the paper
stops moving.
Using Short Tear-Off
When you are finished printing, the short tear-off feature automatically
feeds the perforation of the continuous paper to the tear-off edge of the
printer cover so that you can tear off the last sheet. When you resume
printing, the printer reverses the paper back to the loading position so
that you can use all of the next sheet.
WARNING: Never use short tear-off with labels.
To use short tear-off, first turn off the printer and turn DIP switch 1-5
off. (See the section on setting DIP switches in Chapter 3.) Then load
continuous paper as usual, but leave the rear section of the printer cover
open so that you can use the cover as a tear-off edge.
Paper Handling
2-15
The short tear-off function operates as follows:
1. The perforation at the end of the last printed page feeds to the tear-off
edge of the printer cover.
2. Tear off the page using the printer cover’s tear-off edge.
3. If you need to adjust the position of the perforation to meet the tearoff edge, use micro-adjustment. This feature adjusts your tear-off
position only when you use it immediately after short tear-off. First,
make sure that the printer is on line and the ON LINE indicator light is
flashing. Then, adjust the position in 2/216th-of-an-inch increments
by pressing the FORM FEED button to feed the paper forward or the
LINE FEED button to feed it backward.
After micro-adjustment, the new tear-off position is reset and remains
valid even after the printer is turned off, reset, or initialized.
4. When you resume printing after tearing off the sheet, the paper
automatically feeds backward to the loading position before printing
begins.
2-16
Paper Handling
You can leave the short tear-off feature turned on (DIP switch 1-5 off)
even when you are using single sheets. When you move the paper release
lever to the single sheet position, short tear-off is disabled.
Printing on Special Paper
In addition to using single sheets and continuous paper, your printer can
also print on a wide variety of paper types, including multi-part forms
and labels. You can even feed envelopes, either manually or with the
optional cut sheet feeder. Before printing on these special types of paper,
however, you need to adjust the paper thickness setting.
The paper thickness lever
To accommodate various thicknesses of paper, the FX printer is equipped
with a paper thickness lever that can be set to eight positions. These
positions are identified by a scale on the printer frame next to the lever.
Before changing the paper thickness setting, first make sure the power is
off and then remove the printer cover.
WARNING: If you’ve been using the printer just before
opening the printer cover, be careful not to touch the print
head because it may be hot.
Select the paper thickness you want according to the figure below. For
normal use, the lever should always be set to position 2 on the scale.
Paper Handling
2-17
For printing on special types of paper, see the table below. It gives you
general guidelines for selecting the right paper thickness lever position to
match your paper.

.
WARNING: Printing past the edge of envelopes, multi-part
forms, labels, or thick paper can damage the print head.
When you print on anything thicker than normal paper, such as
envelopes or multi-part forms, be absolutely sure that your printing stays
within the printable area of the paper. See page 2-20 and Appendix A for
more about the printable area of the paper.
Multi-part forms
Your printer can also use continuous multi-part forms. These multiple
forms should have no more than four parts including the original.
Note: Multi-part forms should not be used with the single sheet
feeding system or the optional cut sheet feeder.
2-18
Paper Handling
You load continuous multi-part paper the same way that you load
continuous paper. See the section on loading continuous paper in this
chapter for details. The only difference is that you need to adjust the
paper thickness lever to suit the thickness of your paper before loading.
See the table above for the correct paper thickness setting.
Labels
If you need to print labels, always choose the type mounted on a
continuous base sheet provided with sprocket holes for use with the
tractor. If you attempt to print labels using the single-sheet feeding
system, labels on a shiny base sheet almost always slip a little.
You load labels the same way that you load continuous paper. See the
section on loading continuous paper in this chapter for details. The only
difference is that you need to adjust the paper thickness lever to match
the thickness of your labels. See the table above for the correct paper
thickness setting.
To remove labels, tear off at a perforation behind the push tractor. Then
take the printer off line and use the FORM FEED button to eject the labels.
WARNING: Never feed the labels backward through the
printer. Labels can easily come off the backing and jam the
printer. Therefore, never use the LOAD/EJECT button to eject
labels or to feed labels backward to the standby position.
Also, never use the short tear-off feature with labels. If a
label does become stuck in the printer mechanism, take the
printer to a qualified service person. Since labels are
especially sensitive to temperature and humidity, always use
them under normal operating conditions.
Envelopes
You can print on a variety of envelopes, including air mail, plain, or
bond. To feed envelopes individually, use the single sheet loading feature.
First, set the paper thickness lever as indicated in the table above. Then,
follow the single sheet loading instructions at the beginning of this
chapter.
Paper Handling
2-19
You can also feed envelopes with the optional cut sheet feeder. See the
section on the cut sheet feeder in Chapter 7. Before loading envelopes
into the cut sheet feeder, you need to adjust the paper thickness lever. See
the table showing envelope types and recommended lever positions on
page 2-18.
WARNING: When printing on envelopes, be sure that your
application program settings keep the printing entirely within
the printable area of the envelopes as shown below.

International character sets
Default character set
When DIP switch 1-1 is on, the user-defined character set is the default.
User-defined characters are maintained in printer memory even when the
power is turned off, so the user-defined character set can be selected
simply by setting this switch to on. However, when this switch is on,
new user-defined characters cannot be defined. See Chapter 4 for more
information on user-defined characters. This switch is effective only in
the Epson ESC/P mode.
Zero character
When DIP switch 1-2 is on, the printer prints slashed zeroes (0). When
the DIP switch is off, the printer prints open zeroes (0). This is useful for
clearly distinguishing between uppercase 0 and zero when printing such
items as program lists.
Character table
When DIP switch 1-3 is on, the Epson Extended Graphics character table
is selected. When it is off, the italics character table is selected. The Epson
Extended Graphics character table contains international accented
characters, Greek characters, and character graphics for printing lines,
comers, and shaded areas. If you have an IBM® computer or an IBM
compatible, select the Epson Extended Graphics table when you wish to
print the character graphics as they are displayed on the screen. Since the
character table setting affects only half of the character table, you can
Using the Printer

still print text if you have selected the Extended Graphics set. Also, you
can still print italics if you use the proper software command. If your
printer is in IBM emulation mode (DIP switch 1-4 on), the graphics
characters are available no matter which character table you select.
The printouts below show which characters are printed in each table.

Note: You may need to use the ESC 6 command to print some of the
Extended Graphics characters. See Appendix B.
Printer mode
When DIP switch 1-4 is on, the printer operates in the IBM emulation
mode. When it is off, the printer operates in the Epson ESC/P mode. In
the IBM emulation mode, DIP switch 1-3 controls the automatic carriage
return. When switch 1-3 is off, a carriage return is added to each line
feed. The functions of DIP switches 1-6, 1-7, and 1-8 are also different
when using the printer in the IBM emulation mode. For details, see the
section on international character sets on the next page.
Short tear-off mode
When DIP switch 1-5 is off, the short tear-off mode is on. This feature
advances the paper so you can tear off the paper, and then reverses the
paper so you can use all of the next sheet. See the section on using short
tear-off in Chapter 2.

Also, in IBM emulation mode (DIP switch 1-4 on), a character set
containing international characters (CG character table 2) is selected
whenever any one of DIP switches 1-6, 1-7, or 1-8 is set to off. If all three
switches are on, CG character table 1 is selected. See Appendix B.
Page length
When DIP switch 2-1 is on, the page length is set to 12 inches. When
it is off, the page length is 11 inches. Other page lengths can be set with
the ESC C and ESC CO commands. See the Command Summary in
Chapter 8.
Using the Printer
3-9
Cut sheet feeder mode
When DIP switch 2-2 is on, you can use your printer’s optional cut sheet
feeder. See Chapter 7 for more information on using a cut sheet feeder
with your printer.
Skip over perforation
When DIP switch 2-3 is on, a one-inch margin is provided between the
last line printed on one page and the first line printed on the next page.
When using continuous paper, this feature causes the printer to stop
printing, skip over the perforation, and then resume printing. If you
adjust your loading position correctly, you can get half of the margin at
the bottom of one page and half at the top of the next page. See the
section on adjusting the loading position later in this chapter.
Note: Most application programs take care of the top and bottom
margins. Only use skip over perforation if your program does not
provide these margins.
Automatic line feed
When DIP switch 2-4 is on, a carriage return code (CR) causes an
automatic line feed. When it is off, line feeds occur only when the printer
receives line feed codes (LF). Since some computers and application
programs automatically add line feeds to carriage returns, the setting you
use depends on your computer and application program.
Selecting Typestyles
Your printer can produce a wide range of typestyles by combining
different character fonts, pitches, widths, and other enhancements. These
features can be selected by using the SelecType feature on your control
panel or by using software commands. This section describes only the
features controlled by SelecType. To use software commands, see the
section on computer-printer communication in Chapter 4 and the
Command Summary in Chapter 8.

Using the Printer
Using SelecType
You can use the SelecType control panel to choose fonts, pitches, and
condensed printing. The settings you select using the SelecType panel
remain valid even after the printer is turned off, reset, or initialized.
However, commands from your software application program
temporarily override the SelecType settings.
Character fonts
The FX-850 and FX-1050 have three built-in character fonts:
ROMAN
!“##$%&-( )*+,- ./0123456789:;<=>?6’ABCDEFGHIJK
LMNCPQRSTUWXYZ[\]^-‘ abcdefghijklmnopqrstuv
WxYZC t 1"

Using the Printer

The draft mode uses fewer dots per character for high-speed printing.
This makes draft ideal for rough drafts and editing work.
Roman and Sans Serif are near letter quality (NLQ) fonts. Near letter
quality takes a little longer to print but produces nicely formed
characters suitable for most documentation requirements.
Characters per inch
For each of the three built-in fonts, you can choose a character size of 10
or 12 characters per inch (cpi), or proportional spacing.
The following printout compares the different types of spacing.
This is Roman printing in 10 cpi.
This is Roman printing in 12 cpi.
This is Roman printing in proportional.
In the 10 and 12 cpi modes, each character is given the same amount of
space. However, in the proportional mode, spacing varies from character
to character. Therefore, a narrow letter like the lowercase i receives less
space than a wide letter like the uppercase W.
Condensed mode
In addition to the two pitches and proportional spacing, you can use the
condensed mode to change the character size. In the condensed mode,
characters are approximately 60% of the width of normal characters.
Condensed printing is very useful for spreadsheets and other applications
where you need to print the maximum amount of information on a page.
Both 10 and 12 cpi can be condensed, but proportional spacing cannot.
The printout below compares normal 10 cpi with condensed 10 cpi.
This is
10 cpi Roman printing.
This is condensed 10 cpi Roman printing.
3-12
Using the Printer
Note: Proportional spacing and condensed mode cannot be combined.
If you select both, only proportional spacing works.
If SelecType does not work
Some application programs are designed to control all typestyle
functions. These programs cancel all previous typestyle settings by
sending certain software commands before printing. Because these
commands cancel SelecType settings, you should use the program’s print
options function instead of SelecType to select your typestyles.
Therefore, if SelecType does not work with a particular application
program, consult the software manual for information on selecting
typestyles. Also, see the section on using the FX with application
software in Chapter 4.
Enhancing Your Printing
SelecType controls the printing style of a whole document. Software
commands, on the other hand, can change anything from a single
character to the entire document. By using software commands, you can
obtain many different printing effects with the FX printer, from arranging
the text on the page to giving extra emphasis to particular words and
phrases. This section shows you the features you may want to select with
your software. Once you have read about the features, you can find
their commands in the Command Summary in Chapter 8. Also, see the
section on computer-printer communication in Chapter 4 for more
information on sending commands to the printer.
Character size
Besides 10 and 12 cpi, condensed printing, and proportional spacing,
software commands also offer two other options: double-wide and
double-high printing.
Using the Printer
3-13
The double-wide mode doubles the width of any size characters. This
mode is useful for such purposes as emphasizing headings in reports and
making displays, but is usually not suitable for large amounts of text.
T h i s
i s
d o u b l e - w i d e -
Another mode for headings and other special uses is double-high:
This is double-high.
Because of its height, you must leave a blank line above a line of doublehigh printing. Otherwise, the double-high letters will overlap the letters
on the previous line.
Double-wide and double-high can be combined to obtain even more
impressive printing results:
Double-high
double-wide
Widening or narrowing the characters also widens or narrows the spaces
between words and letters. Because word processors usually create a left
margin by printing spaces, you may need to change the number of
characters on a line to keep the margins correct if you change widths.
For example, a left margin of 10 characters at 10 cpi is the same as a fivespace margin using double-wide characters.
Emphasized and double-strike printing
Emphasized and double-strike printing give your documents added
emphasis. In emphasized mode, the FX prints each character twice as the
print head moves across the paper, with the second printed slightly to the
right of the first. This process produces darker, more fully formed
characters.
3-14
Using the Printer
In double-strike mode, the printer prints each character twice, the second
time slightly below the first, making the text bolder. For even greater
boldness, you can combine emphasized and double-strike. (Double-strike
cannot be combined with NLQ mode, however.)
Italic printing
You can use italic characters for special emphasis or as an alternative
typeface. ESC 4 turns on the italic mode even if the current DIP switch
setting is set to the Epson Extended Graphics character table.
This sentence is in italics.
Underlining
The underline mode automatically underlines any piece of text. It
underlines spaces, subscripts, and superscripts. (The printer does not,
however, underline horizontal tabs.)
Superscripts and subscripts
Superscripts and subscripts can be used for printing footnote numbers
and mathematical formulas. The example below combines underlining,
superscripts, and subscripts in a mathematical formula.
a v e r a g e = ( a 1 + . . . . . . . . . . . . . . . . + a n )
n
Selecting typestyles with Master Select
Your printer has a special command called Master Select that allows you
to choose many possible combinations of nine different modes. To send
Master Select codes to the printer, you must first choose the mode
combination you want. The modes you can choose from are 10 cpi, 12
cpi, proportional, condensed, emphasized, double-strike, double-wide,
italics, and underline.

To send the Master Select codes to your printer in a decimal format, for
example, you send the codes 27, 33, and then whatever value you choose
for the variable n.
The variable n is a number that identifies the typestyle or combination of
typestyles. To find the value of n, look at the Master Select table below
and add up either the decimal or hexadecimal numbers for the features
you want.
Master Select Table
For example, if you want to print a title using double-wide 12 cpi
characters in double-strike mode, you would add these three decimal
numbers together to calculate the value of n:
12 cpi
Double-strike
Double-wide
3-16

n = 49
Using the Printer
After calculating the value of n, you use the Master Select command to
send the value to the printer. To send the Master Select command for
double-wide, 12 cpi, and double-strike, you would use the decimal codes
27, 33, and 49.

Consider these things when you use the Master Select command:
l
Master Select cancels any of the listed features that you do not set.
For example, if you have already set 12 cpi, and you try to use
Master Select to set emphasized double-strike only, the character
width is reset to 10 cpi.
l
Proportional overrides 10 cpi, 12 cpi, and condensed.
l
Double-strike cannot be combined with NLQ mode.
Print quality and font are not part of Master Select and must be set
separately, using either SelecType or the ESC x and ESC k commands.
The method you use to send the Master Select codes to the printer is
determined by your application software. For more information on
sending commands to your printer, see the Computer-Printer
Communications section in Chapter 4 and the Command Summary
in Chapter 8.

Using the FX with Application Programs
Now that you’ve set up and tested the printer, you need to start using it
with your application programs.
Most application programs let you specify the type of printer you’re
using so that the program can take full advantage of the printer’s
features. Many programs provide an installation or setup procedure that
presents a list of printers to choose from. If your application program
has a printer selection menu, use the instructions below.
Using printer selection menus
If your software has a printer selection menu, simply choose FX-850 or
FX-1050. If the menu does not list either of these printers, choose one of
the following. They are listed in order of preference.
FX-850
FX-86e
EX-800
FX-85
FX-80 +
FX-80

Draft printer
If you plan to use the IBM emulation mode, choose IBM Proprinter (if
you have an FX-850), IBM Proprinter XL (if you have an FX-1050), IBM
Graphics printer, or IBM printer, in that order of preference.
Note: If your application program does not list the FX-850 or FX-1050,
you may want to contact the software manufacturer to see if an
update is available.
4-2
Using Software and Graphics
A quick test
After setting up your application program, print a sample document to
make sure the program and the FX are communicating properly. If the
document doesn’t print correctly, recheck the program’s printer selection
and installation procedure. If you’re still having trouble printing, consult
the troubleshooting section in Chapter 6.
Using word processors
Word processors usually let you use a fixed set of printer features by
placing markers around the text to be altered. When the document is
printed, the markers are recognized and translated into suitable
commands for your printer. On your screen some programs show the
markers; others display the text as it will appear-for example, in bold
or italics. This method is normally restricted to features that can be
found on almost all printers, such as bold and underlining.
Some word processing programs also let you insert printer commands in
your text. These commands may or may not be visible on your screen.
This method has the advantage of allowing you to use any printer
command, not just a limited set. To make use of it, however, you need to
understand how to use your printer’s commands. Check the manual for
your word processor to see if you can place printer commands in your
text, and then see the section in this chapter on computer-printer
communications.
Using spreadsheets
Although spreadsheets seldom use as many printing styles as word
processors, they do have some very specific requirements.
If your spreadsheet program provides a list of printers, use the list on
page 4-2 to find the proper selection. If your spreadsheet doesn’t have a
printer setup routine, read the program’s manual carefully for
information on printing.
A major concern for printing spreadsheets is the width of the printer. The
FX-850 is an 80-column printer, and the FX-1050 is a 136-column printer.
You can, however, increase the number of characters on a line by
selecting 12 cpi, condensed mode, or both from the SelecType control
Using Software and Graphics
4-3
panel. The table below shows you many characters you can fit on a line
using these options. If your spreadsheet asks the number of columns
your printer can print, decide which mode you will use and supply the
appropriate number from this table.
Unlike word processors, spreadsheet programs usually don’t let you
change printer commands within a spreadsheet. Instead, one style or
mode of printing is used for the whole spreadsheet. With the FX, there
are two main ways of sending commands to control the printing of a
spreadsheet. The first method is to choose condensed from the SelecType
control panel.
For the second method, look in the manual for your spreadsheet to find
out how to send printer commands. Then look in the Command
Summary in Chapter 8 to find the proper codes to send.
For example, your spreadsheet might use a “setup string” to send printer
commands. To prepare a setup string for 12 cpi condensed, you would
look up the proper command in the Command Summary. The command
for 12 cpi is ESC M, and the command for condensed is SI. Because most
spreadsheets use the decimal equivalent for the commands, (also given in
the Command Summary), a setup string for 12 cpi condensed might look
like this:
/027/077/015
The number 027 is for the escape code, 077 is for M, and 015 is for SI
(condensed).
4-4
Using Software and Graphics
Using graphics software
The FX is capable of producing finely detailed graphic images. Although
the section on graphics later in this chapter gives specific information on
the graphics commands, the easiest way to take advantage of the FX’s
capabilities is with one of the many graphics programs available.
When buying graphics software, always make sure the program has an
option to print on an FX printer. Any program with an option for an FX
printer should give excellent results, using different dot densities to
produce a realistic scale of grays.
Most graphics programs have a printer selection procedure, in which
case you should check the lists on page 4-2 to find the proper selection.
Computer-Printer Communication
Your computer communicates with your printer using a standardized set
of numbered codes called ASCII codes (American Standard Code for
Information Interchange). When you press the letter A on the keyboard,
it is translated into the ASCII code for A, transmitted to a peripheral
device such as your computer screen or your printer, and then converted
back into the letter A.
There are ASCII codes for all the letters in the alphabet, both uppercase
and lowercase letters, and for the numbers 0 through 9. The ASCII set of
codes also includes most punctuation marks and some codes that control
printer functions.
In the Command Summary in Chapter 8, each code is expressed three
different ways: as an ASCII character, as a decimal number, and as a
hexadecimal (base 16) number. For example, the uppercase letter A is
represented as the ASCII character A, the decimal number 65, and the
hexadecimal number 41. The numbering system you use depends on
your software and your preferences.
All letters, numbers, and punctuation marks are assigned decimal
numbers from 32 through 255. ASCII codes with decimal values of less
than 32 are called control codes, because they control the operation of
Using Software and Graphics
4-5
your printer and other peripherals. These ASCII characters do not
usually have corresponding keys on the keyboard and cannot be printed
as characters by your printer.
Escape sequences
Although there are more than 30 control codes available to control the
operation of your printer, many more codes are required to run today’s
sophisticated printers. Therefore, ASCII codes are grouped in sequences
to represent certain functions. These code sequences use the ASCII codes
with decimal values of 32 through 255, normally reserved for characters
and punctuation, to control printer functions. This is done by first
sending a standard code to tell the printer that the codes that follow are
to be used as control codes, not as characters or punctuation.
The standard code that is sent at the beginning of one of these code
sequences is the Escape code, decimal value 27. Any sequence of codes
starting with the Escape code is called an Escape sequence. You will
probably see Escape written in different ways-such as ESC, ESC, and
ESCape-in various manuals. In this manual it is in the form of ESC
when used within a command.
Printer commands
In order for the printer to recognize the instructions it receives, ASCII
codes must be sent in a specific format, called a command. An Escape
sequence is a command, as is any ASCII code or sequence of codes that
instructs the printer to carry out a particular function. Your software
continually sends commands to your printer and your computer screen.
These commands instruct the printer to perform such actions as print in
a particular typeface, feed the paper a certain amount after printing each
line, and start printing on a particular spot on the page.
Some software programs let you send these commands yourself. This is a
powerful feature because it allows you to enhance your text in ways that
may not normally be available through the software. For example, many
word processing programs do not offer italics. By inserting a command
in your document, however, you can use italics anywhere you like. The
4-6
Using Software and Graphics
commands that your printer recognizes are listed in the Command
Summary in Chapter 8 and on the Quick Reference card at the back of
this manual.
Using the Command Summary
The commands listed in the Command Summary in Chapter 8 consist of
various combinations of ASCII codes. You can use either the ASCII
characters or their decimal or hexadecimal equivalents. For example, the
command to turn on subscript is ESC S1 in ASCII characters. The
decimal format for this command is 27 83 01, and the hexadecimal
format is 1B 53 01.
In the Command Summary, commands are grouped by the printer
functions they control, such as character pitch, print enhancement, and
graphics. You can also look up commands in the list of software
commands in numerical order at the beginning of the Command
Summary. This list gives you page number references for the commands.
Some commands include a variable, such as the letter n. For example,
the command for selecting or cancelling double-high mode is ESC w n.
When n = 1, double-high mode is turned on, and when n = 0, it is
turned off. In the Command Summary, variables are printed in italics to
distinguish them from ASCII characters.
Sending printer commands from within your software program
How you format commands depends on the software program you are
using. Some software programs accept only the decimal format, while
others require certain punctuation. Some programs don’t let you insert
printer commands at all.
If your software does allow you to send commands to the printer, use the
Command Summary to find the command you want to send. Your
software manual should explain exactly what format and punctuation
are required.
Using Software and Graphics
4-7
Dot Graphics
The dot graphics mode allows your FX printer to produce pictures,
graphs, charts, or almost any other pictorial material you can devise.
Because many commercial software programs use graphics, you may be
able to print pictures and graphs like the ones on this and the following
page simply by giving your software a few instructions.
4-8
Using Software and Graphics
The quickest and easiest way to print graphics on your printer is to use a
commercial graphics program. With such programs you usually create
an image on your monitor and then give a command to send the image
to the printer.
If you use commercial software that produces graphics, all you need to
know about dot graphics is how to use the software. If, on the other
hand, you wish to do your own programming or merely wish to
understand how the FX prints graphics, read on.
The print head
To understand dot graphics you need to know a little about how the FX’s
print head works.
The print head has nine pins. As the print head moves across the page,
electrical impulses cause the pins to fire. Each time a pin fires, it strikes
the inked ribbon and presses it against the paper to produce a small dot.
As the head moves across the paper, the pins fire time after time in
different patterns to produce letters, numbers, or symbols.
Using Software and Graphics
4-9
The print head is able to print graphics in addition to text because
graphic images are formed on the FX about the same way that pictures in
newspapers and magazines are printed. If you look closely at a
newspaper photograph, you can see that it is made up of many small
dots. The FX also forms its images with patterns of dots. The images
printed by the FX can be as finely detailed as the ones at the beginning of
this section.
In its main graphics mode the FX prints one column of dots for each code
it receives, and it uses only the top eight of the nine pins. Therefore,
your graphics program must send codes for dot patterns, one number for
each column in a line. For each of those columns the print head prints
the pattern of dots you have specified.
To print figures taller than eight dots, the print head makes more than
one pass. The printer prints one line, then advances the paper and prints
another, just as it does with text.
To keep the print head from leaving gaps between the graphics lines as it
does between the text lines, the line spacing must be changed to eliminate
the space between lines. With a change in line spacing, the FX can print
finely detailed graphic images made up of adjacent lines, each no more
than 8/72-inch tall.
Each pass of the print head prints one piece of the total pattern, which
can be as tall or short and as wide or narrow as you desire. You don’t
have to fill the whole page or even an entire line with your graphics
figures. In fact, you can use as little or as much space as you like for a
figure and put it anywhere on the page.
Pin labels
The graphics mode requires a method to tell the printer which pins to fire
in each column. Since there are 256 possible combinations of eight pins,
you need a numbering system that allows you to use a single number to
specify which of the 256 possible patterns you want. By labelling each
pin with its own number, you can use a numbering system that allows
you to specify exactly which pins should be fired.
To fire any one pin, you send its number, according to the numbering
system shown in the figure on the next page. To fire more than one pin at
4-10
Using Software and Graphics
the same time, add up the numbers of the pins and send the sum to the
printer. Therefore, with these labels for the pins, you fire the top pin by
sending 128. To fire the bottom pin, you send 1. If you want to fire only
the top and bottom pins, you simply add 128 and 1, and send 129.
By adding the appropriate label numbers together, you can fire any
combination of pins. The figure below shows three examples of how to
calculate the number that fires a particular pattern of pins.
128

134
With this numbering system, any combination of the eight pins adds up
to a decimal number between 0 and 255, and no numbers are duplicated.
Before you can put these numbers in a graphics program, however, you
need to know the format for graphics commands.
Graphics commands
Graphics commands are quite different from most other commands. For
most of the other modes, such as emphasized and double-wide, one
command turns the mode on and another turns it off. For graphics, the
command is more complicated because the command that turns on a
graphics mode also specifies how many columns of graphics will be
printed. After the printer receives this command, it interprets the next
numbers as pin patterns and prints them on the paper.
The graphics command format
There are several different graphics commands giving different horizontal
dot densities and printing speeds. Because the format is almost the same
for all the commands, however, the example here keeps things simple by
using only the single-density graphics command, ESC K. In singledensity graphics, there are 60 dots per inch horizontally.
Using Software and Graphics
4-11
The command to enter single-density graphics mode is ESC K n1 n2. In
BASIC the command is given in this format:
LPRINT CHR$(27);1tKf';CHR$(nZ);CHR$( n2);
In this command, ESC K selects single-density graphics, and n1 and n2
specify the number of columns to reserve for graphics.
Column reservation numbers
The graphics command requires more than one number to specify how
many columns to reserve because although one line can use thousands of
columns, the FX does not use numbers larger than 255 (decimal).
Therefore, the graphics mode command uses two numbers for reserving
columns.
To figure n1 and n2, divide the total number of columns by 256. The
result is n2; the remainder iS n1. Since the command is set up for two
numbers, you must supply two numbers even if you need only one.
When you need fewer than 256 columns, just make n1 the number of
columns you are reserving and make n2 a zero.
For example, if you wish to send 1632 columns of graphics data, n1
should be 96 and n2 should be 6 because 1632 = 96 + (6 X 256).
Graphics data
After receiving a graphics command such as ESC K n1 n2, the printer
prints the number of codes specified by n1 and n2 as graphics data, no
matter what codes they are. This means that you must be sure to supply
exactly the right amount of graphics data. If you supply too little, the
printer stops and waits for more data and seems to be locked. The next
data sent will then be printed as graphics, even if it is really text. On the
other hand, if you supply too much graphics data, the excess will be
printed as regular text.
Graphics programming
Here is an example that shows how a graphics command, column
reservation numbers, and data can be used to print a single line of
graphics. The example is a BASIC program. You can, of course, use
another programming language. The principles are the same.
4-12
Using Software and Graphics
The first line of the program specifies single-density graphics for 40
columns:
100 LPRINT CHR$(27);"K";CHR$(@);CHR$(@;
The second line is the data that is printed as pin patterns. It uses the
number 74 to produce one of the patterns shown above. The FOR-NEXT
loop sends 40 columns of data.
Here is the second line of data:
2@g FOR X=1 TO 48: LPRINT CHR$(7L,);: NEXT X
That is the whole program. In BASIC, semicolons at the ends of the lines
are very important; they prevent the computer from sending other codes
after the ones you specify. In other languages you may have to use a
special command to send a single code at a time. Run the program to see
the result below. Although it is not as interesting as the examples at the
beginning of this chapter, it shows exactly how the graphics mode works.
........
. . . . ....
. .....................
. . . ........
. . . . . .........
WIDTH statements
Some software programs (including most versions of BASIC)
automatically insert carriage return and line feed codes after every 80 or
130 characters. This is usually no problem with text, but can spoil your
graphics. Two extra columns of graphics are printed in the middle of the
ones you send, and two data numbers are left over and printed as text.
In some versions of BASIC you can prevent unwanted control codes in
graphics by putting a WIDTH statement at the beginning of all graphics
programs. The format in many forms of BASIC is either WIDTH
“LPT1:“, 255 or WIDTH LPRINT 255. Check your software manual for
the proper format.
Printing taller patterns
The next example shows how several lines of graphics can be formed
into a figure taller than eight dots. It uses programming techniques for
producing textured or repetitive patterns.

If you run the program, you will see how it combines six print lines into
a pattern.
There are five basic steps that the program goes through to produce this
kind of pattern.
1. The computer is prevented from adding any extra characters by the
WIDTH statement (line 100).
2. The line spacing is changed to 8/72 of an inch-the height of the dot
patterns used in the program (line 110).
3. The program goes through the graphics commands the required
number of times (lines 120 and 170).
4. A new graphics command is used for each line printed (lines 130-160).
This part of the program is similar to the last example, but two
columns are printed each time through the loop making a total of
100.
4-14
Using Software and Graphics
5. The last important thing to do is to reset the printer to its default
settings, including the normal line spacing (line 180).
Notice that the graphics command (ESC K) can be in effect for only one
print line. To print more than one line of graphics, the graphics
command must be issued before each line.
Density varieties
Although all the examples so far in this section have been in the singledensity graphics mode, there are seven other eight-pin densities and two
that use all nine pins.
Nine-pin graphics is not necessary for most uses, but you can find the
command (ESC *) in the Command Summary in Chapter 8. The four
most common eight-pin modes are ESC K, ESC L, ESC Y, and ESC Z.
There is also a general purpose command for any of the eight-pin
graphics modes: ESC *. This command is used in the same way as the
individual commands, except that before n1 and n2 you must send the
code for the graphics mode required.
The different graphics modes are summarized in the following table:

*Adjacent dots cannot be printed in this mode.
Modes 4, 5, 6, and 7 are special modes that alter the horizontal density
to give the proportions of a computer monitor (the CRT modes) or to
match the vertical density so as to give round circles (the plotter mode).
In two modes, high-speed double-density and quadruple-density, the
print head cannot print two consecutive dots with the same pin, so it
Using Software and Graphics
4-15
prints dots in only half the possible dot positions in any one row. The
higher density means that the resolution of the pattern is better than in
single-density mode. When you design patterns in these two modes,
however, you must make sure that no dots overlap.
Reassigning a graphics mode
Another graphics command lets you assign a different eight-pin graphics
mode to one of the specific eight-pin graphics commands. You can use
this command with graphics software programs to quickly change the
density and proportions of your printouts. Changing the graphics option
changes the width without changing the height.
The command for reassigning a graphics mode is ESC ? c m. In this
command, c is a letter designating one of the four alternate graphics
codes (K, L, Y, or Z) and m is the mode number of the new mode, as
listed in the table on page 4-15.
For example, to change the ESC K command to select the CRT I screen
graphics mode, the command in BASIC is’ the following:
LPRINTCHR$(27);"?K";CHR$(4);
A little experimentation should tell you whether the reassigning
command can improve your graphics printouts.
Designing your own graphics
This section takes you through the development of a graphics program.
The example is not especially complicated, but it does include the same
steps you would use for a more complex figure.
You should plan your figure with dots on graph paper, but before beginning
to place the dots, you must decide which graphics density you want. The
figure on the next page shows the differences between three common
modes.

In this figure you can see the main rules for graphic design in the three
densities:
l
l
l
In single-density no dots can be placed on vertical lines.
In high-speed double-density, dots can be placed on vertical lines, but
no dots can overlap.
In double-density, dots can be placed on vertical lines, and they can
overlap.
Now look at the high-speed double-density design below. It should point
you in the right direction for your own work.
Using Software and Graphics
4-17
After plotting the dots on a grid, you calculate the numbers for each pin
pattern by dividing the design grid into separate print lines. For the
arrow design, the grid was divided into two lines, each seven dots high.
Then each column was examined to calculate the graphics data. The
results for the first line are shown below. The pin values are on the left
and the sums at the bottom of each column.

The numbers for the second line were calculated in the same way. Once
the numbers for the pin patterns are calculated, they are put in the
program in DATA statements, separated by commas.
The program works in a similar way to the example before. This time it
selects 7/72-inch line spacing because only seven pins are used. Because
the data is not repetitive, each column of graphics data is read from the
DATA statements and sent to the printer. The design is 41 dot positions
wide. Therefore both lines 130 and 140 use the number 41.

User-Defined Characters
The FX has several hundred different characters stored in its ROM (Read
Only Memory). Although this number includes draft, italic,
international, Epson Extended Graphics, and NLQ (near letter quality)
characters, sometimes you may want to have a few more. For those
occasions when you need a special character or a few letters in a different
typeface, the FX allows you to create your own characters and print
them just as if they were ordinary letters.
You can make the task of defining characters easier by using a
commercial software program that either assists you in creating
Using Software and Graphics
4-19
characters or simply supplies you with sets of characters already created.
Also, some popular commercial software programs take advantage of
the printer’s user-defined character function to enhance printouts. These
characters are sometimes called download characters.
Defining your own characters
The printout below displays a few such characters to give you an idea of
what can be done, but remember that since these characters are truly
user-defined, you can create whatever you need or want.
DIP switch 1-1 must be off before you can create a user-defined
character. The procedure for designing a character is a simple three-step
process:
1. Plan your character.
2. Run a program to test your work and calculate the required DATA
numbers.
3. Run another program to put the character in your printer’s memory
for use whenever you need it.
Once you define a character, you can print it in either draft or NLQ. If
you print it in NLQ, the printer adds dots to make the character more
fully formed.
After you have created your own characters with these programs, certain
keys that you seldom use generate the user-defined characters. For
example, you can press the ( key to print !$ .
You can create any type of character. The only restriction is that the
characters you define must follow the same rules that govern the rest of
the characters printed by the FX. They must fit into an 11 x 9 matrix, no
dot can overlap another (in draft mode), and either the top or the
bottom row must be empty.
4-20
Using Software and Graphics
Suppose you want to print the scientific symbol for the planet Mercury
Although the FX has a number of special symbols, that is not one of
them. First, use a grid like the one below to plan where to place the dots.

123456789
Because the last two columns are reserved for the space between
characters, they are not included in the grid. And since most characters
do not use the bottom two rows, there is a heavy line to indicate the
usual lower limit for an FX character.
When you place your dots on this grid, remember that dots cannot go on
horizontal lines, but they can go on vertical lines. If they overlap other
dots, they will not be printed in draft, only in NLQ. As you design your
characters, draw the dots as large as the circles you see in the example
below. (The printer prints dots, but it is best to use circles when planning
your characters.)

Running the program
Now run the program. For each of the nine columns, the program asks
for the numbers of the rows in which you want dots to appear. Enter the
row numbers one at a time, pressing the Enter key after each one. When
you have entered all the numbers for a column or when you want no
dots in a column, press Enter without a number. Remember that the
vertical lines in the grid are the even-numbered columns.
To see the program produce the Mercury symbol, run the program and
follow these instructions:
1. When the screen message asks what rows have dots in column 1,
press Enter to indicate that no dots go in that column.
2. For column 2 (the vertical line) press 7, Enter, 5, and Enter again to
indicate that you want dots in rows 7 and 5. Then press Enter alone
to indicate that no more dots go in column 2.
3. For column 3 press 8, 6, 4, and 2, and Enter after each of them. Press
Enter to finish with column 3 and go on to column 4. (The rest of
the directions assume that you know to press Enter after each
number and one extra time to end the entries for each column.)
4. For column 4 enter 6, 4, and 2.
5. For column 5 enter 6, 4, 3, 2, and 1.
6. For column 6 enter 6, 4, and 2.
7. For column 7 enter 8, 6, 4, and 2.
8. For column 8 enter 7 and 5.
9. For column 9 press Enter only.
Now wait a moment for your computer to calculate the dot patterns and
your printer to print the new character in two different typestyles and

next program. You should get the printout you see below:
When you get to this point with a character of your own, you see how it
looks. If you want to make any changes, move the dots as needed and

To use this program for your own character or characters, change the
DATA numbers in line 210 by substituting the numbers generated by the
first program when you created your own character. If you have created
more than one character, put the DATA numbers for each character on a
separate line as you see in the example below:
210 DATA 112,8,~,138,116,138,8,8,112
220 DATA 56,68,146,40,13jiY,40,130,68,56
Check your work by making sure that there are nine numbers in each
line and that the numbers are separated by commas. Also make the
change in line 100 explained below.
This program is designed for defining up to 6 characters. Line 100 states
K=l, but to define more than one character, use the total number of
characters you are defining instead of the 1 in that line. You can actually
define as many as 256 characters, but if you define more than six
characters, you have to change a few lines in the program.
Using Software and Graphics
4-25
Running the program
When you run this second program, it prints six characters, then redefines some or all of them and prints them again, as in the example
below.
: ; .:., = ;. ;j
: ;*a!$?
When printed by your own program, these two lines provide you with a
key to the characters your FX can now print. When you press the key for
one of the characters in the top row, the printer prints the corresponding
character in the bottom row. In the example above, if you type < your
FX prints B (although your screen continues to show the character < ).
If you have designed a few characters and want to use them with your
word processing program, for example, just run the second definition
program before you start using your word processing program. Then use
the two-line printout as your guide to tell you which keys to press for
your new characters.

3. To turn off the data dump mode, press the ON LINE button to take the
printer off line, and then turn off the printer. (The data dump mode
can also be cancelled by sending an INIT signal from the computer.)
Look at the data dump shown in Step 2. By comparing the characters
printed in the right column with the printout of the hexadecimal codes,
you can check what codes are being sent to the printer. If characters are
printable, they appear as their true ASCII characters. Nonprintable
codes, such as control codes, are represented by dots.
As an example of how to interpret a data dump printout, look at the first
three hex codes on the second line of the printout sample (20 20 54). Each
hex 20 represents a space, while hex 54 represents the letter T. Check the
second line of the right column and you will find the letter T preceded by
two spaces.

The Cut Sheet Feeder
The optional cut sheet feeder #7339 (for the FX-850) or #7340 (for the FX1050) gives you easier and more efficient handling of single sheet paper.
Up to 150 sheets of standard bond paper can be fed automatically into
the printer without reloading. The cut sheet feeder can also automatically
feed envelopes.
Installation
Attach the assembled cut sheet feeder as follows.
1. Turn off the printer.
2. Remove the printer cover and the paper guide.
3. Make sure the paper release lever is pushed back to the single sheet
paper position.
7-2
Using Printer Options
Remove the paper tension unit by pressing open the release levers
and, at the same time, lifting up on the front of the unit.
5. Tilt the feeder forward slightly to fit the notches at the base of the
unit over the pins on the printer; then tilt the unit back until it rests
on top of the printer.
Using Printer Options
7-3
6. Detach the front section of the printer cover.
7. After raising the cut sheet feeder’s paper path guide, attach the front
cover to the printer. Then close the paper path guide.
Setting the sheet feeder mode
To allow your printer to use the cut sheet feeder you need to set DIP
switch 2-2 to on. If you need more information on how to do this, see
the section on setting DIP switches in Chapter 3. To set the cut sheet
feeder mode, do the following:
l
l
l
Turn the printer off.
Set DIP switch 2-2 to the on position using a pointed object, such as
the tip of a pencil.
Turn the printer back on.
Always change DIP switch settings with the printer power turned off.
The printer checks and recognizes new settings only at the time the
power is turned on.
7-4
Using Printer Options
Recommended paper
Paper:
For best results, use typewriter-quality paper. If you use
paper with a glossy or textured surface, you should test it
before regular use. The cut sheet feeder can hold up to 150
sheets of paper. Do not use multiple-part forms or labels.
Envelopes:
You can print on air mail, plain, or bond envelopes. The cut
sheet feeder can hold up to 25 plain or bond envelopes, or
30 air mail envelopes. Before printing on envelopes, you
need to set the paper thickness lever. See the section on
printing on special paper in Chapter 2.
1.
77
WARNING: Printing past the edge of envelopes or heavy
paper can damage the print head. Be absolutely sure that the
printing is no closer than l/4 of an inch to the edges.
Paper loading
To load paper, follow the steps below.
1. Pull the paper set lever all the way forward until the paper supports
retract and lock open to allow for paper loading. Make sure that the
two small front levers are up when using normal paper.
Using Printer Options
7-5
Slide the left paper guide all the way to the left and slide the right
paper guide to roughly match the width of your paper.
3. Take a stack of paper and fan it as shown. This keeps the sheets from
sticking to one another. Tap the side and bottom of the paper on a
flat surface to even up the stack.
7-6
Using Printer Options
4. Insert the paper between the paper guides, aligning it with the left
edge of the guide. Then adjust the right paper guide until the paper is
held firmly (but not so tightly that it causes the paper to bunch).
5. Push the paper set lever back to clamp the paper against the guide
rollers. The lever will not close completely if you use too much
paper. If the lever does not close, remove some paper from the stack
and try again.
Using Printer Options
7-7
Envelope loading
Envelopes are loaded in much the same way as regular paper. To load
envelopes, you need to do the following:
1. Set the paper thickness lever to match the thickness of your
envelopes. (For specific information on paper thickness settings, see
the section on printing with special paper in Chapter 2.)
2. Follow steps 1 through 5 of the previous section on paper loading to
load envelopes. You can load up to 25 plain or bond envelopes, or 30
air mail envelopes.
3. Push down on the two front levers until they lock into position.
Using the cut sheet feeder
After loading paper into the cut sheet feeder, make sure the ON LINE light
is on. Once the printer is in the sheet feeder mode, a new sheet of paper
loads automatically whenever a printable character or line feed
command is sent to the printer.
When the cut sheet feeder runs out of paper, it stops paper feeding and
the PAPER OUT light comes on. To start printing again, load more paper
7-8
Using Printer Options
sand then press the ON LINE button. The printer starts printing from the
point at which it was stopped.
If you turn your printer off during the time the printer detects a paper
out or paper jam condition, any data remaining in the printer’s buffer is
discarded.
Software operation
This command causes the printer to eject the sheet in the printer without
loading the next sheet:
FF
form feed
The sheet in the printer is automatically ejected and the next sheet is
loaded if the paper reaches the bottom of the print area when any of the
following line feed commands is used:
LF
line feed; advances the paper by one line
VT
vertical tab; advances the paper to the next vertical tab
position
ESC J
performs line feed in units of 1/216 of an inch.
Setting up your software
When you switch between continuous paper and cut sheet feeder paper
you usually need to change the settings of your software program.
Because of the physical requirements of feeding a single sheet of paper,
sheet feeders create a top and bottom margin on each sheet. To work
properly, your software program needs to know how many printable
lines are available on the page.
Paper comes in many different sizes and it is sometimes difficult to know
exactly how many printable lines per page you have. When you perform
a self test in sheet feeder mode, the printer automatically counts and
prints the number of lines that are available on any size of paper. This is
the number of lines you should use as the page length in your software
setup. See the following section on the self test in cut sheet feeder mode
for more details.
Using Printer Options
7-9
In addition to the number of printable lines, which your software may
refer to as page length or form length, you may need to set the top
margin, the bottom margin, and the actual number of lines to be printed
on the page. The cut sheet feeder normally creates a two-line unprintable
top margin. Therefore, if you want a total top margin of six lines (one
inch), set the top margin in your software to four lines. The sheet feeder
usually creates an unprintable bottom margin of about three lines, so to
create a total bottom margin of six lines, set the bottom margin in your
software to three lines. With a total page length of 61 printable lines, for
example, the number of printed lines per page would be 54 (9 inches).
Some software designed only for printing on continuous forms does not
use the form feed command recommended for sheet feeder operation.
The software may not have a sheet feeder setup mode or allow for
margin settings, and may only use line feeds to advance to the next form.
Your sheet feeder can still work with most of these applications. Simply
insert the paper you will be using into the sheet feeder, use the self test to
print out the number of printable lines, and then use that number of lines
as the page length setting in your software. If you change paper sizes,
repeat this process. Your sheet feeder will work as if it were feeding a
continuous form. If your software does not allow you to set the page
length, consult your software manufacturer.
The following is a typical example of a software setup required for
proper operation of your cut sheet feeder. Not all software is set up the
same, so a bit of experimentation may be required before you find the
best equivalent settings to use. To maintain 54 printed lines per page:

Using Printer Options
Many word processors and other software programs give you two ways
to change these settings:
l
l
You can change the settings in each individual file you print.
You can change the program’s default settings so that every time you
use the program, these new settings are in effect.
If your program has additional features, such as headers and footers, you
have to compensate accordingly.
Control panel operation
All of the functions from the control panel are available in cut sheet
feeder mode. You can use micro-adjustment to change the loading
position immediately after loading a sheet using the single sheet insertion
method described on page 7-14. Micro-adjustment sets a new sheet
loading position for as long as the power remains on. If the power is
turned off, the loading position returns to the factory setting. Changing
the loading position with micro-adjustment affects the number of lines
per page. You may need to change your software margin settings again
for this new page length. See the section on micro-adjustment in
Chapter 2.
Testing the printer in the cut sheet feeder mode
The printer’s built-in self test in the cut sheet feeder mode is slightly
different from that of the original self test. To test the printer in cut sheet
feeder mode, load the paper you will be using into the paper bin. Hold
down the LINE FEED or FORM FEED button and turn the power switch on
as described in Chapter 1.
When you perform the cut sheet feeder self test, the printer counts the
number of lines on the page and prints out this number at the bottom of
the first page as shown in the following figure. The number of lines
counted by the printer becomes the new default page length setting for
the cut sheet feeder mode. You can override this setting, however, using
software commands.
The self test is especially useful when you want to change the page length
settings for your application program, because it gives you a quick count
of the number of lines on the page.
Using Printer Options
7-11
Below is a portion of the first page of a self test in cut sheet feeder mode.
The remainder of the self test is similar to the original self test described
in Chapter 1.
WARNING: Never perform the self test on envelopes.
Switching from the cut sheet feeder to continuous paper
The FX allows you to switch between cut sheet feeder paper and
continuous paper easily without having to remove either the feeder or
the continuous paper supply. To switch between these two paper feeding
methods, follow the steps below.
1. Make sure the continuous paper is already loaded and in a standby
position, as explained in the section on switching between single
sheets and continuous paper in Chapter 2.
2. Install the cut sheet feeder as described in this section, making sure
that DIP switch 2-2 is set to on, and that the paper release lever is
pushed all the way back to the single sheet position.
7-12
3. To switch from cut sheet feeder operation to continuous paper, pull
the paper release lever all the way forward to the continuous paper
position. You do not need to change the DIP switch setting.
4. Raise the paper path guide on the cut sheet feeder until it clicks open, as
shown below. This guide directs the flow of continuous paper out of the
front of the printer.
5. With the paper release lever foward, the control panel functions
normally. This allows you to use micro-adjustment to adjust the
loading position of your paper.
6. To switch back to the cut sheet feeder, push the LOAD/EJECT button
until the continuous paper feeds backward out of the paper path and
into a standby position. Push the paper release lever back to put the
printer into the sheet feeder mode, and then close the paper path
guide.
Using Printer Options
7-13
Single sheet insertion
Your cut sheet feeder also has a single sheet loading feature. This feature
allows you to switch to a different type of paper (such as letterhead)
without replacing the supply of paper that is loaded in your cut sheet
feeder. Single sheet insertion is especially useful because it allows you to
use micro-adjustment to change your cut sheet feeder loading position.
1. Press the ON LINE button to take the printer off line.
2. Align the single sheet to be fed with the marking on the left paper
guide, and then slide the sheet into the printer path until you feel
resistance.
3. Press the LOAD/EJECT button to load the sheet.
Note: If you want to use single sheet insertion for two or more
consecutive pages, pull the cut sheet feeder’s paper set levers forward;
otherwise, the next sheet is loaded from paper stored in the cut sheet
feeder bin.
4. Press the ON LINE button to put the printer on line. Now you can use
micro-adjustment to change the loading position for your cut sheet
feeder. See the section on micro-adjustment in Chapter 2.
7-14
Using Printer Options
The Pull Tractor
The optional pull tractor (#7311 for the FX-850 and #7312 for the
FX-1050) provides optimum continuous paper handling. The pull tractor
is especially useful with continuous multi-part forms and labels. For best
results, use the pull tractor along with the built-in push tractor, as
described in this section.
After making sure that you have both parts of the pull tractor option as
shown below, remove the packing material and save it in case you need
to ship the unit later.
Caution: The short tear-off function cannot be used with the pull
tractor. Before you start printing with the pull tractor, make sure that
DIP switch 1-5 is set to on. (Short tear-off is turned off only when the
DIP switch is set to on. See the section on setting DIP switches in
Chapter 3.)
Installation and use
After making sure that the printer is turned off, install and use the pull
tractor as follows:
1. Remove the printer cover and the paper guide and install the paper
rest if you haven’t already. (See Chapter 2.)
Using Printer Options
7-15
2. Remove the paper tension unit by pressing open the release levers
and lifting up the front of the unit at the same time.
3. Hold the pull tractor with the gears to the right and fit the rear
notches on the tractor over the rear mounting pins on the printer as
shown below.
7-16
Using Printer Options
4. Tilt the tractor unit toward you until the front latches click in place
over the front mounting pins of the printer.
5. Now load paper as described in the section on loading continuous
paper in Chapter 2. However, position the left sprocket unit about
1/4 of an inch from the left before locking it in place.
6. After the paper is loaded in the push tractor, make sure the printer is
off line and then press the FORM FEED button. This advances the
paper one page so you can fit the paper onto the pull tractor.
Caution: Never use the platen knob to feed the paper while the printer
is turned on. If you need to adjust the loading position, use the microadjustment function described in Chapter 2.
7. Open the sprocket covers, and release the sprocket lock levers.
Using Printer Options
7-17
8. Move the sprocket units to match the width of the paper and adjust
the paper supports so they are evenly placed between the sprocket
units. (There is only one paper support on the FX-850 pull tractor.)
9. Fit the holes of the paper over the tractor pins of the sprocket units,
adjusting the position of the sprocket units as necessary.
7-18
Using Printer Options
10. If the paper does not fit exactly onto the tractor pins, press in on the
pull tractor feed knob and turn it in the desired direction.

they meet at about the middle of the paper’s width.
15. Install the pull tractor cover.
7-20
Using Printer Options
16. Press the ON LINE button to put the printer on line. Now you are
ready to begin printing.
When you are finished printing
The short tear-off function cannot be used with the pull tractor. If you
want to tear off the last printed page at its perforation, press the ON LINE
button to take the printer off line and press the FORM FEED button to feed
the paper forward an additional page before tearing off the paper.
Using the pull tractor alone
If you wish, you can use the pull tractor without using the push tractor.
To do this, feed the paper from the rear, above the metal guide, and then
load it. Be sure to pull the paper release lever forward to the continuous
paper position after you load the paper.
Removing the pull tractor
After turning off the printer and removing the pull tractor cover, remove
the pull tractor as follows:
1. Pressing the tabs on the pull tractor, tilt it back and lift it off the printer.
Using Printer Options
7-21
2. Replace the paper tension unit as shown below.
3. Now you are ready to use either single sheets or the push tractor.
Interface Boards
There are a number of optional interfaces that can be used to supplement
the capabilities of your printer’s built-in parallel interface.
Choosing an interface
Optional interfaces can be divided into three main categories:
l
l
IEEE-488 interfaces offer standardized connections, trouble-free
operation, and the ability to connect computers, printers, and other
devices on the same line so that they can share data freely.
Buffered parallel interfaces give the printer more memory and free up
the computer for other tasks when printing large amounts of text or
graphics. With a buffered parallel interface, you can increase the
printer’s data buffering capacity to 32 Kbytes (about 10 pages).
Parallel interfaces also offer the advantage of trouble-free operation
combined with standardized connectors.
7-22
Using Printer Options
l
Serial interfaces are necessary if your computer is not equipped with
a parallel interface or if you need an interface that conforms to the
Current Loop standard instead of the RS-232C. In addition, all
available serial interface boards provide user-selectable baud rates
and data word structures. These interfaces also offer some combination of the following features: X-on/X-off data communication
protocol, loopback self-test modes, and data buffers that increase the
printer’s buffering capacity to either 32 Kbytes or 128 Kbytes.
If you are still unsure whether you need an optional interface, or would
like to know more about interfaces, contact your Epson dealer.

number where it is described.
The Quick Reference card at the end of the book also contains a list of
the commands divided by topic, with page number references that direct
you to full explanations of the commands. The numerical list and the
Quick Reference card also show the differences between the Epson mode
and the IBM emulation mode.
The second part of this appendix lists and describes Epson mode
commands and IBM emulation mode commands separately; the
commands are divided into the following subjects:
Printer Operation
Data Control
Vertical Motion
Horizontal Motion
Overall Printing Style
Print Size
Print Enhancement
Word Processing
Character Sets
User-Defined Characters
Graphics
Each command has a format section and a comment section. The format
section gives the ASCII, decimal, and hexadecimal values for the
command; the comment section describes the effect of the command and
gives any additional information necessary for using it.
All three formats are equivalent, and it should be easy to pick the one
most suited to your purpose.
Note: Some application programs can use control key sequences. See
the Control Key chart on page 8-3 for information on using these.
Command Summary
8-1
The simplest type of command consists of a single character to be sent to
the printer. For instance, to print in condensed mode the code format is:
ASCII code: SI
15
Decimal:
Hexadecimal: 0F
This code can be sent from a program by sending the code 15 directly.
More complex commands consist of two or more character codes. For
example, to print in double-wide mode the code format is the following:
ASCII code:
Decimal:
Hexadecimal:
ESC
W
27
1B
87
57
n
n
n
In this case n can be either 1 or 0, to begin or end double-wide printing.
You can use either of the following commands to turn ON double-wide
print from BASIC:
LPRINT CHR$(27);CHR!$(87);CHR!§(l)
LPRINT CHR!§(27);“W”; CHR!$( 1)
For the following commands that use only 0 or 1 for the variable, either
the ASCII codes 1 and 0 or the ASCII characters 1 and 0 can be used:
ESC s, ESC U, ESC x, ESC p, ESC W, ESC S, ESC-, ESC w, and
ESC %
For example, in BASIC you can turn on double-high with either of these
statements:
LPRINT CHR$(27); “w”; CHR$( 1)
LPRINT CHR!$(27);“w”;“l”
8-2
Command Summary
Control key chart
Some application programs can use control key codes for decimal values
0 through 27. The table below gives you the proper values. The Control
Key column indicates that you press the control key at the same time
you press the key for the letter or symbol in that column. For example,
you press the control key and A at the same time to send the value 1.
Note: Many programs use the control keys for other purposes. Also,
some programs do not use all these keys.

The variable n is the number of lines skipped between the last line
printed on one page and the first line on the next page. For example,
with the standard settings for line spacing (l/6-inch), and page length
(66 lines), ESC N 6 causes the FX to print 60 lines and then skip 6. DIP
switch 2-3 performs the same function. This setting is cancelled by
ESC 0 and also by ESC C or ESC C 0. The value of n must be from 1
to 127.

Comments:
This sequence specifies the distance from the currently set left margin
that subsequent characters are to be printed, using this formula: total
number of dots = n1 + (n2 X 256). Each unit equals 1/60th of an
inch. The sequence is ignored and the previous setting remains
effective if the position specified is beyond the right margin. This
command applies to both draft and NLQ.

Comments:
Determines the position (relative to the current position) at which
printing of following data will start. To find n1 and n2, first calculate
the displacement required in 1/120ths of an inch. Send the resulting number
using this formula: total number of dots = n1 + (n2 X 256). If the
displacement is to the left, subtract the number from 65536 before you
use the formula. The command is ignored if it would move the print
position outside the current margins. This command applies to both
draft and NLQ.

The width of proportional characters varies from character to
character. Therefore, a narrow letter like i receives less space than a
wide letter like W. The proportional widths are given in the character
tables, which appear in Appendix B. This command overrides
condensed, 10 cpi, and 12 cpi.

The column heading “Direction” refers to the direction of signal flow
as viewed from the printer.
“Return” denotes the twisted-pair return, to be connected at signal
ground level. For the interface wiring, be sure to use a twisted-pair
cable for each signal and to complete the connection on the return
side. These cables should be shielded and connected to the chassis of
the host computer and the printer.
All interface conditions are based on TTL level. Both the rise and the
fall times of each signal must be less than 0.2 microseconds.
Data transfer must be carried out by observing the ACKNLG or
BUSY signal. Data transfer to this printer can be carried out only
after receipt of the ACKNLG signal or when the level of the BUSY
signal is LOW.
Printing enabled/disabled signals and control conditions
The following table shows the relationship between printing being
enabled or disabled, the on line/off line status, and the receipt of the data

Proportional Width Table
This table lists the widths of your printer’s proportional characters. The
values given are in 120ths of an inch. (For example, a value of 12 is
12/120ths of an inch.) You may need to enter these widths into a special
table for your word processing program so it can calculate the number of
proportional characters that will fit on a line.
The characters with no code indicated are international characters or
graphics. See the table in the section on international character sets in
Chapter 3 for the relevant codes for the international characters. Also,
see the descriptions of the ESC R and ESC t commands in the Command
Summary for information on how to use these characters.
The following width table shows each code (hexadecimal), its character,
and its width. If there are two numbers in the width column, the second
one is for the italic character.

Character Tables
These character tables are selected by setting DIP switch 1-3 or using the
ESC t software command. For the Epson Extended Graphics character
table, use of the ESC 6 or ESC 7 software command lets you select
whether to print hex codes 80 to 9F as characters (ESC 6) or control
codes (ESC 7).

Glossary
Note that these definitions apply specifically to printers. If a word is
italicized, see that topic for more information.
application program
A program that helps you carry out a particular task, such as word
processing or financial planning.
ASCII
American Standard Code for Information Interchange. A standardized
coding system for assigning numerical codes to letters and symbols.
automatic line feed
When this feature is turned on using a DIP switch, each carriage return
code (CR) is automatically accompanied by a line feed (LF) code.
baud rate
A measure of the speed of data transmission. Usually equivalent to bits
per second.
bidirectional printing
Printing in which the print head goes from left to right only on every
other line. On the other lines, it goes from right to left. This increases the
speed of printing because the head prints in both directions.
binary
See number systems.
bit
A binary digit (0 or l), which is the smallest unit of information used by
a printer or computer. See also number systems.
buffer
See memory.
byte
A unit of information consisting of eight bits.
Glossary
GL-1
carriage return
The control code that returns the print position to the left margin. When
issued together with a line feed, the print position moves to the left
margin of the next line. In bidirectional printing, the print head may not
actually move to the left margin.
characters per inch (cpi)
A measure of the size of text characters, often referred to as pitch. 10 cpi
(also called pica) is often the standard or default setting.
character set
A collection of letters, numbers, and symbols that provides you with the
characters used in a particular language.
condensed
Printing in which each character is approximately 60% of the width of
standard characters. Useful for fitting wide tables or spreadsheets onto
the paper.
continuous paper
Paper that has sprocket-feed holes on each side, is perforated between
pages, and comes in a folded stack. Also called fanfold paper.
control code
Besides the codes for printable characters, the ASCII standard also
includes 33 other codes called control codes. These control codes perform
such functions as sounding the beeper and performing a carriage return
or line feed.
cut sheet feeder (CSF)
An optional, detachable device that automatically feeds single sheets of
paper into the printer.
data dump
A troubleshooting feature. When the printer is in data dump mode, each
code that it receives is printed in hexadecimal notation as well as the
ASCII codes that stand for the characters. Sometimes called hex dump.
decimal
See number systems.
GL-2
Glossary
default
A value or setting that takes effect when the equipment is turned on,
reset, or initialized.
DIP switches
Small switches in a printer that control various printer functions and set
the default status of the printer when it is turned on or initialized. DIP
stands for Dual In-line Package.
dot graphics
A graphic design formed by patterns of dots.
dot matrix
A method of printing in which each letter or symbol is formed by a
pattern (matrix) of individual dots.
double-high printing
Printing in which each character is twice as high as normal.
double-strike printing
A way of producing bolder characters. Each character is printed twice;
the second time, the dots are printed slightly below the original dots.
Can only be used in draft mode.
double-wide printing
A print width in which each character is twice as wide as normal
characters. (Double-wide was formerly known as expanded.)
draft
One of two print qualities available on your printer. Draft uses a
minimum number of dots per character for high-speed printing. See also
near letter quality.
emphasized printing
A way of producing darker characters. Each character is printed twice,
with the second slightly to the right of the first.
Epson Extended Graphics
The Epson Extended Graphics character table contains international
accented characters, Greek characters, and character graphics for
printing lines, comers, and shaded areas.
Glossary
GL-3
ESC (escape)
A special control code used to begin most printer commands.
ESC/P
Abbreviation for Epson Standard Code for Printers. The system of
commands lets you control your printer using your computer’s software.
It is standard for all Epson printers and supported by most applications
software for personal computers.
font
A style of type designated by a family name.
form
In printer terminology, a form is normally the equivalent of a page.
form feed
A control code and a control panel button that advances the paper to the
top of the next form.
hexadecimal (hex)
See number systems.
initialize
To establish the initial default status of the printer by turning the printer
on or sending an INIT signal.
interface
The connection between the computer and the printer. A parallel
interface transmits data one character or code at a time, and a serial
interface transmits data one bit at a time.
italic
A typestyle in which the characters slant. This sentence is italicized.
near letter quality (NLQ)
One of two print qualities available on your printer. Near letter quality
reduces the print speed and increases the number of dots per character to
increase the print quality. See also draft.
line feed
A control code and a control panel button that advances the paper one
line space.

Glossary
memory
The printer, like a computer, has a memory. When you print a file from a
computer, the contents of the file are transferred quickly from the
computer’s memory to the printer’s memory. The printer then prints
information from its own memory at a much slower rate. This way of
printing frees the computer to do other work while the printer is still
working. The printer memory is sometimes called the buffer.
micro-adjustment
A feature that adjusts the paper loading and tear-off positions.
number systems
Three number systems are commonly used with printers:
decimal is base 10 and uses the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.
(This is the most familiar system.)
hexadecimal (hex) is base 16 and uses the digits 0, 1, 2, 3, 4, 5, 6, 7, 8,
9, A, B, C, D, E, and F. This is frequently used by programmers. Any
decimal number between 0 and 255 can be expressed by a two-digit
hex number.
binary is base 2 and uses only the digits 0 and 1. All information in
computer systems is handled in binary form to represent electrical
signals that are on or off. A binary digit is often called a bit; any
decimal number between 0 and 255 can be expressed by an eight-bit
binary number.
on line
When the printer is on line, it can communicate with the computer
connected to it,
paper-out sensor
A small switch behind the platen that sends a signal when it is not in
contact with paper, causing the PAPER OUT light to go on.
paper tension unit
The part of the printer that fits on top of the platen to ensure proper
paper feed tension.
parallel interface
See interface.
Glossary
GL-5
Parity is a method for a computer and printer to check the reliability of
data transmission.
pitch
Indicates the number of characters per inch (cpi). The standard is 10
pitch.
platen
The black roller that provides a backing for the printing.
print quality
Your printer has two types of print quality: draft and near letter quality
(NLQ). Draft is for high-speed, draft-quality jobs; NLQ is for final,
polished documents.
proportional printing
Printing in which the width of the character varies from character to
character. For example, an uppercase W receives much more space than
a lowercase i. The result looks more like a typeset book than a
typewritten draft.
push tractor
The built-in device that feeds continuous paper through the printer.
Random Access Memory. The portion of the printer’s memory used as a
buffer and for storing user-defined characters. All data stored in RAM is
lost when the printer is turned off.
reset
To return a printer to its defaults, by either a command, an INIT signal,
or by turning the printer off and on.
self test
A method of checking the operation of the printer. When the self test is
run, the printer prints out its current DIP switch settings and the
characters that are stored in its ROM.
serial interface
See interface.
GL-6
Glossary
top of form position
The position on the paper that the printer recognizes as the first printable
line. For single sheets, this is the position to which the paper is
automatically loaded. For continuous paper, this position can set to the
current paper position by turning the printer off and on.
user-defined characters
Characters that are defined and stored in the printer by the user. Also
known as download characters.
short tear-off
A feature that automatically feeds the perforation of continuous paper to
the tear-off position and then feeds the paper back to the loading
position. This position can be adjusted by using the micro-adjustment
feature.
