LOCATING THE PRINTER

Before you start unpacking and setting up your printer, make sure that you have a suitable place on which to locate it. By “a suitable place”, we mean: l

A firm, level surface which is fairly vibration-free l

Away from excessive heat (such as direct sunlight, heaters, etc) l

Away from excessive humidity l

Away from excessive dust l

Supply it “clean” electricity. Don’t connect it to the same circuit as a large, noise-producing appliance such as a refrigerator. l

Make sure the line voltage is within 10% of the voltage specified on the identification plate. l

A location with sufficient space to locate the printer and any paper to be fed into it, as well as the printed paper coming out. l

If you are using a parallel connection to your computer, make sure that it is within 2m (6ft) of the printer (an RS-232 connection using the optional

RS-232 interface can be made over longer distances).

UNPACKING AND INSPECTION

Check the carton contents

Now unpack the contents of the printer shipping carton, and check each item in the box against Figure l- 1 to make sure that you have everything (there should be five items).

If any of these items are missing, contact your supplier.

Figwe 7-7. Check to make sure you have all five items: 1) Printer, 2) Paper guide, 3) Platen knob, 4) Ribbon cartridge, and 5) User’s manual.

The optional accessories which you may have ordered with your printer are: l

SETTING UP

Place the printer in the position where it is going to be permanently sited, and remove all packing material from inside the top cover. This packing material is intended to prevent damage to the printer in transit. You may like to keep this packing with the printer carton if you intend transporting the printer for use at a different location.

Mount the platen knob

The platen knob is packed into a recess of the white foam packing material which held your printer inside the printer carton. Be careful to remove the knob before disposing of the packing.

Mount the platen knob on the shaft on the right-hand side of the printer. Turn the knob on the shaft before pushing the knob fully into position.

3. The ribbon should pass between the print head and the print head shield

(see Figure l-6).

Figure 7-6. Pass the ribbon between the print head and print head shield

Now, hold the top cover upright and engage the tabs at the back. Then swing the front edge down until the cover is closed.

Leave the top cover closed during normal operation. It keeps out dust and dirt and reduces the printer’s operating sounds. Open the cover only to change the ribbon or make an adjustment.

Connection

Connect the printer to your computer, using a standard parallel-type cable.

On a PC or PC/AT-type computer, this means that you use the 25way D- type connector at the computer end, and the Amphenol-type 36-way connector at the printer end. The pinouts of the printer’s connector are given in Chapter 8 if you need a cable for connection to another computer.

Plug the printer into a suitable mains outlet. However, DO NOT turn on the power switch at the front of the printer yet.

Figure 1-7. Connecting the interface cable

If you want to use the optional serial interface, slide out the parallel interface board by gripping the flips on both sides. Then insert the optional serial interface board all the way, as shown in Figure l-8.

2. Make sure that the release lever is down. button to park the paper, then move the release lever downwards.

3. Adjust the paper guides to match the size of paper you will be using (re- membering that printing will start some distance from the left-hand edge of the carriage).

4. Place a single sheet between the guides, placing the side on which you want to print towards the back of the printer. Gently push the paper down in the guides until you feel it stop.

Figure l-10. Loading a single sheet

5. Turn on the power using the switch at the front of the printer. The printer will beep, indicating that no paper is in position for printing. The orange

POWER indicator also flashes to show this.

6. Now press the ( s~&$~#F ) button. The paper bail will move clear of the paper, and the paper will be fed and adjusted past the print head to a position ready for printing. The paper bail will be moved back to grip the paper against the platen, and the print head will move to the start position.

Manual loading

It is also possible to load paper manually while the printer’s power is off. The procedure is:

1. Place the paper guide in position, locating the lugs on the bottom of the assembly into the slots on the rear cover of the printer.

2. Check that printer power is off and the release lever at the back of the printer is down.

3. Open the top cover, then move the bail lever on top of the printer forward to open the paper bail.

4. Adjust the paper guides to match the size of paper you will be using (re- membering that printing will start some distance from the left-hand edge -- of the carriage).

5. Place a single sheet between the guides, placing the side on which you want to print towards the back of the printer. Gently push the paper down in the guides until you feel it stop.

6. Turn the platen knob clockwise until the front edge of the paper comes out from under the top cover.

7. If the paper is not straight, move the release lever to me up position, straighten the paper by hand, then move the release lever back down.

8. Move the bail lever back to close the paper bail.

LOADING AND PARKING FANFOLD FORMS

Fanfold forms have holes along the sides and perforations between the sheets. They are also called sprocket forms, punched forms, or

just

plain

“computer paper”. This printer accepts forms up to 16” wide. Fanfold forms are loaded, parked, and unparked as explained next.

Loading the paper from the rear of the printer

You can load the fanfold paper either from the rear or from the bottom of the printer. If you are going to load the paper from the bottom read the next section.

1. Place a stack of fanfold paper behind and at least one page-length below the printer.

2. Turn the printer’s power OFF.

3. Push the release lever to the upward position. This has the effect of releasing the paper from the platen roller, and engaging the tractor,feed.

4. Remove the paper guide and put it aside for the moment.

5. Remove the rear cover. Grip it by its rear edge and lift upwards and backwards as in Figure 1- 11. q

Figure l-11. Opening the rear cover

6. With the sprocket covers open, thread the paper over the sprockets, aligning holes with the pins on the sprockets.

7. Mount the new top cover.

Paper parking

After loading fanfold paper from the rear of the printer, you do not have to unload it when you want to print on a single sheet. The printer will “park” it for you if you follow the procedure below.

1. Paper parking starts with power ON, fanfold paper loaded in printing position, the release lever up.

2. Press the (

ON LINE

> button on the control panel to set the printer off- line

(ON LINE indicator off).

3. Tear off the printed form at the last perforation, leaving not more than about half a page showing above the top cover. If necessary, press the

(PAPER FEED)

button to feed paper forward until a perforation is located just above the top cover, and tear there.

4. Press the ( sE&~&FT )button on the control panel.

The printer will automatically feed the fanfold form backward until the paper is completely free of the platen.

When you want to resume using fanfold paper, the procedure is as follows.

1. Remove all single sheets from the printer.

2. Mount the paper guide in the horizontal position.

3. Move the release lever to the up position.

4. Press the ( s~&!&$F ) button. The printer will automatically feed the parked fanfold paper into position for printing.

ADJUSTING THE PRINTING GAP

The distance between the print head and the platen can be adjusted to accommodate different paper thicknesses. To make this adjustment, remove the top cover. The adjustment lever is located near the right end of the paper bail. Pulling the adjustment lever upwards narrows the gap; pushing it downwards widens the gap.

There are five positions; you can feel the lever clicking into each position.

The second position from the top is the one most commonly used for single sheets of paper. Try different positions until you get the best printing results. i-

BUTTONS AND INDICATORS

The printer is equipped with five buttons on the control panel: from right to left they are,(

ON LINE ],(PAPER FEED>

and( SEX&CT )(largerbuttons), and (PITCH) and (3VEJ (smaller buttons).

The following is a brief guide to the buttons and indicators on the control panel.

Figure 2-1. Control panel

ON LINE button

The (

ON LINE

) button sets the printer on-line and off-line. The state changes each time you press the button.

In the on-line state the printer receives data from the computer and prints the data. In the off-line state the printer stops printing and sends the computer a signal indicating that it cannot accept data.

The printer powers up in the on-line state if paper is present. If paper is not present, the printer powers up off-line with the

POWER indicator flashing.

When you load paper the

POWER indicator stops flashing, but the printer remains off-line. To start printing you must press the (

ON LINE

) button go on-line.

The three main times when you will want to press the(

ON LINE

)button are: l

Before and after any other panel operation

The other panel buttons operate only in the off-line state. First press the

( ON LINE

)button to go off-line, then perform the panel operation, then press the

( ON LINE

) button again to go back on-line. l

To pause during printing

If you press the

( ON LINE

) button during printing, the printer stops printing and goes off-line, allowing you to check the printout or change a control panel setting. Printing resumes when you press the

( ON LINE >

button again to go back on-line. l

To cut fanfold forms at the end of printing

When using fanfold forms, if you hold the

( ON LINE

)button down for one second, in addition to go off-line the printer feeds the paper about two inches forward, allowing you to cut it off just below the last line printed.

When you press the

( ON LINE

)button again to go back on-line, the paper feeds backward about one inch, stopping in the right place to resume printing.

I

PAPER FEED button

If you press this button in off-line, the paper feeds forward. If you hold this button down, the printer performs consecutive line feeds.

While you are feeding lines, if you

also

press the

(

ON LINE

> button, the paper will feed to the top of the next page. This is explained later.

SET/EJECT PARK button

Pressing this button causes the printer to execute paper loading if the paper has not loaded while in the off-line state.

If the paper has been loaded, this button causes the printer in different functions depending on the release lever position.

If the release lever is set to the upward position for the fanfold forms, this button operates to park the fanfold forms to the backward position.

If the release lever is set to the downward position for the single sheets, pressing this button ejects the paper.

This button has no effect if the optional pull tractor unit is mounted.

PRINT PITCH button

This button selects the print pitch that will be printed. Remember that the printer must be off-line for you to do this. Successive presses of this button will illuminate (and select) the following options in this order:

Pitch

Pica

Elite

Condensed pica

Condensed elite

Pica proportional

Elite proportional

Indicator(s)

PICA

ELITE

PICA, COND

ELITE, COND

PICA, PROP

ELITE, PROP

Holding down this button will cycle continuously between these options.

q

NLQ TYPE STYLE button

This button selects the font style to be printed. Draft style is always selected at power-up. To change to one of the NLQ (near letter quality) styles, set the beside the desired selection illuminate. The selections cycle in the following order:

Font style

Draft

Courier

Courier italic

Sanserif

Sanserif italic

Orator

Orator italic

Indicator(s)

(all indicators off)

COURIER

COURIER, ITALIC

SANSERIF

SANSERIF, ITALIC

ORATOR

ORATOR, ITALIC

-I

Holding down this button will cycle continuously between these options.

The Orator style is unique in two ways. First, it is a lot larger (higher) than the other styles. This makes it a good choice for labels and other text requiring high visibility. A little extra line spacing helps when Orator is used. Second, there are two versions of the Orator font style: one prints small capitals in place of lower-case letters; the other prints lower-case letters, but without descenders. The other font styles do not have a small-capitals option. Lower case always prints as lower case.

You get the small capitals when you select Orator from the control panel.

The font style can also be selected by printer commands given in Chapter 4.

Printer commands enable you to select both Orator styles, and also draft italic, which cannot be selected from the control panel.

POWER-UP FUNCTIONS

In addition to their normal functions, all the control panel buttons have special functions that operate if you hold them down while switching power on.

--F-A

Sray in p&d pitch

igure 2-2. Power-up functions of control panel

If the printer is turned on while the (

ON LINE

) button is pressed, the printer will enter the short self-test mode. The printer will start printing as soon as the (

ON LINE

) button is released, and will print the version number of the printer’s ROM, followed by six lines of the character set.

Each line will be offset by one character from the one before it. The final result will be something like the following.

Figure Z-3. Short self-test

Since the test print occupies the whole width of the carriage, it is recommended that the printer is loaded with continuous stationery to avoid possible damage to the print head and/or platen.

Long test mode

If the printer is turned on while the

(PAPER FEED)

button is pressed, the printer will enter the long self-test mode. The printer will start printing as soon as the

(PAPER FEED)

button is released, and will print the version number of the printer’s ROM, followed by the whole character set printed in each font styles and pitch available.

The test cycles endlessly. To stop the test you must switch power off.

Since the test print occupies the whole width of the carriage, it is recommended that the printer is loaded with continuous stationery to avoid possible damage to the print head and/orplaten. In addition, the total number of lines printed is considerable, more than can be accomodated on a single sheet, so fanfold paper is certainly suggested for this test.

Print area test mode

If you want to know how many lines on your paper can be printed, try to run up, the printer will enter the print area test mode. The printer will print the first line message, then prints the last line message on your single sheet after feeding the paper to the bottom of the paper.

If you have loaded the fanfold paper, the printer shows only the first line.

Stay in panel pitch

By holding the (PITCH) button down during power-up, you can prevent software interference with the print pitch selected from the control panel.

You will hear an acknowledging beep as power comes on.

After the beep tone, you can set the printer off-line, select a print pitch, then return to on-line and start printing. The pitch you selected will not be reset or otherwise changed by any commands your software may issue.

Stay in panel style

ference with the font style selected from the control panel. There will be an acknowledging beep, after which you can set the printer off-line, select a font style, then return to the on-line state and start printing. The selected font style will not be changed by any commands sent by software.

Stay in panel pitch and style

If you want to protect both the pitch and font style settings from software be a little long acknowledging beep.

Pressing these buttons during power-up does not prevent you from making any number of changes later from the control panel.

Hexadecimal dump

This feature is useful for programmers who are debugging printing programs and want to see the actual codes the printer is receiving. (Some computers change the codes the programmer intended.)

In this mode, all received data will be printed in a hexadecimal dump format, rather than the control codes being acted on as command codes.

This mode is accessed with the following procedure:

1. Holding

both the (PAPER FEED)

and ( sE?X&cT ) buttons down, turn power ON. A beep tone will be heard.

2. Start printing. In place of the usual printout you will get a formatted dump showing exactly what data the printer receives. Each line presents sixteen characters, their hexadecimal codes to the left and printable characters printed on the right.

3. At the end of the hexadecimal dump, set the printer off-line with the

(

ON LINE

Ibutton. This is necessary to print the last line.

The following BASIC program is a simple test you can run in hexadecimal mode:

10 FOR I=0 TO 255

20 LPRINT CHR$(I);

30 NEXT I

40 LPRINT

50 END

If your system passes the codes directly to the printer without changing them, you will get a printout like Figure 2-4.

When the IBM-PC BASIC interpreter sends hex code OD (carriage return) it adds an extra hex OA (iine feed). Hex code 1A (end-of-file) also gets special treatment: the interpreter does not send it at all. This can cause problems that generate graphics or download character data, but there is a solution. Try changing line 20 in the preceding program and adding the coding shown below.

SWITCH COMBINATION FUNCTIONS

Several additional functions can be obtained by pressing the control panel buttons in combinations.

-FF-A

Top of form

Clearing the buffer

If you are using single sheets, this operation ejects the current page. If you are using fanfold forms, it feeds to the top of the next page.

1. Press the (

ON LINE

) button to set the printer off-line.

2. Press the

(PAPER FEED)

button and hold it down. The printer will start performing successive line feeds.

3. Still holding the

(PAPER FEED)

button down, press the (

ON LINE )

button, then release both buttons. The printer will smoothly eject the current page.

Top of form

When you turn on printer power, the top-of-form position is automatically set to the current position. If this is not where you want the top of the page to be, you can change the top-of-form position as follows.

1. Press the (

ON LINE

> button to set the printer off-line.

2. Move the paper to the desired top-of-form position by pressing the

(PAPER FEED]

button, orbyperforming a forward or reverse micro-feed.

3. Press and hold the (

ON LINE

> button.

4. Press and hold the (PITCH) button.

5. Release both buttons at the same time. The printer will beep to indicate that the top-of-form position has been set.

Forward micro-feed

For line alignment, you can feed the paper forward in very small increments as follows:

1. Press the (

ON LINE

) button to set the printer off-line.

2. Press the (

ON LINE

) button again and hold it down.

3. Press the

(PAPER FEED)

button. The paper will start advancing in a series of small steps. When you want to stop, release both buttons.

Reverse micro-feed

You can also feed the paper in small increments in reverse, to return to a higher position on the same page.

Note:With fanfold forms, do not try to return to a previous page. The perforation may catch inside the printer.

Press the

( ON LINE

1 button to set the printer off-line.

2. Press the (

ON LINE

) button again and hold it down.

3. Press the ( s~&/A@~ )button. The paper will start moving backwards in a series of small steps. When you want to stop, release both buttons.

Clearing the buffer

When DIP switch 2-l is ON, the printer stores received data in a large memory buffer. This creates a problem when you want to abandon a printing job and restart: the printer may be holding much more data in its buffer than it has actually printed, and this unprinted data must be cleared out before restarting. Turning power off is one way to clear the buffer, but there is another way:

1. Halt the printing program on the computer. If printing stops immediately, the buffer is clear and the rest of this procedure is unnecessary. If printing does not stop, continue as follows:

2. Press the (

ON LINE

) button to set the printer off-line. Printing will now stop, but there may be data remaining in the buffer.

3. Press and hold the

( ON LINE

) button. down. In about three seconds you will hear a beep tone signaling that the buffer has been cleared.

5. Release these buttons, make any necessary control panel settings, then set the printer back on-line.

It is essential to halt the printing program on the computer before you go off- line. Otherwise, when you go back on-line the computer will start sending data again and the printer will continue printing, with missing data where the buffer was cleared.

Chapter 3 D/P SWITCH SETTINGS

The bank of DIP (Dual In-line Package) switches inside the printer is used for various functions.

This chapter explains where the DIP switches are located, and how to use them.

. .._

LOCATION OF THE DIP SWITCHES

When you remove the printer’s cover and look inside, you will see on the green board at the bottom of the printer two groups of small white switches marked DSWl and DSW2. These are the printer’s DIP switches. DSWl has eight switches, named l- 1 to l-8 from left to right. DS W2 has four switches named 2-l to 2-4.

Figure 3-7. DIP switches

For all switches, the ON position is towards the back of the printer and the

OFF position is towards the front. To set a DIP switch, use a ballpoint pen or other small implement to move the switch to the ON or OFF position.

The printer’s power should be off when you set the DIP switches. Settings made while power is on do not take effect until power is switched off, then on again, because the printer reads the DIP switches only at power-up.

FUNCTIONS OF THE DIP SWITCHES

The printer is delivered with all DIP switch set to the ON position. These are the standard settings. By changing the settings, you can alter various printer functions to match your requirements. The following questions will help you make the right settings.

2-2

2-3

2-4

International character set

Switch l-l:

Is the page length of your paper 11 inches or 12 inches?

Leave this switch ON if you will be using 1 l-inch forms. Move it to the OFF position if you will be using 12-inch forms.

Switch 1-2:

Do you want an automatic carriage return?

Leave this switch ON. The printer will automatically perform a carriage return by moving to the left margin at each line feed. Even if your software sends a separate carriage-return code, an extra carriage return does no harm because two consecutive carriage returns are the same as one. Very few programs require this switch to be OFF.

Switch 1-3: Which type of printing area format do you want to use for single sheets?

This printer can use two types of printing area format for single sheets. By putting the switch ON (“A type”), the top of the first line of printing will start to one inch from the top of the paper, and the printed area will end to print one inch from the bottom of the paper.

By putting the switch OFF (“B type”), the top of the first line of printing will start l/6 inch from the top of the paper, and the printed area will end l/3 inch from the bottom of the paper.

Switch 1-4: Are you going to use the automatic sheet feeder (ASF)?

To use the automatic sheet feeder, move this switch to the OFF position.

Otherwise leave it ON.

Switch 1-5: Do you want the printer to stop printing at the end of the paper, or to keep printing?

Leave this switch ON except when you need to print very close to the end of the paper. When this switch is OFF the printer ignores the paper-out detector and prints down to (and beyond) the bottom edge.

Switch 1-6: Do you want to use the printer in standard mode or IBMmode?

Select the mode compatible with your computer and software. In standard mode the printer operates like the Epson FX- 1050. In IBM mode it operates like the IBM Proprinter XL. The ON position selects standard mode. The

OFF position selects IBM mode.

Switch 1-7: The action of this switch depends on the mode chosen with switch 1-6.

If you selected standard mode, do you want italics or graphic char- actes?

Leave this switch ON to print italics in the standard character set. If you set this switch to the OFF position, in place of italics you will get the graphic characters, international characters, and mathematical symbols of IBM character set #2. See Chapter 9, character codes 128 to 254.

If you selected IBM mode, do you want IBM character set #l or #2?

ON selects character set #2, which is for computers with an E-bit interface

(the most common kind). OFF sclccts character set #l, for computers with a 7-bit interface.

Switch 1-8: Do you want an automatic line feed?

If you leave this switch at the ON position, a separate line-feed code is required to obtain a line feed.

If you move this switch to the OFF position, the printer performs both a carriage return and line feed each time it receives a carriage-return code.

Most computer systems send a line feed code, or both a carriage return and line feed, at the end of each line, so this switch should be left ON.

If you get double line spacing when you expect single spacing, or if lines overprint each other, try changing the setting of this switch.

Switch 2-1: Does your software download new characters to the printer?

To download characters this switch must be OFF. The printer then uses its

RAM memory for storing character patterns and provides only a one-line print buffer. If you leave this switch ON the printer uses its RAM memory as an input buffer, allowing the computer to send data faster than the printer prints.

Switches 2-2 to 2-4: Do you want an international character set?

International character sets differ in their assignment of 14 character codes.

See the character tables at the back of this manual. With the DIP switches you can select one of eight character sets as follows:

* Denmark/Norway when switch l-6 is OFF and switch l-7 is ON.

Chapter 4 PRINTER CONTROL COMMANDS

The printer has two emulation modes: Standard mode and IBM mode.

In standard mode, the printer emulates the functions of the Epson FX- 1050.

In IBM mode, the printer emulates the IBM Proprinter XL. Additional command codes are included as a superset of these emulations.

The emulation is changed by means of DIP switch 1-6. When ON, the printer will be in standard mode, and when OFF, the printer will be in IBM emulation mode (see Chapter 3). It is not possible to change the emulation mode by means of software control or the front control panel.

This chapter describes the printer’s control commands. Some commands are common to both the standard and IBMmodes. In the descriptions of the commands, all commands will be given by function. The name of each command is followed by a table like the one below:

Each data byte indicates eight vertical dots, with the MSB being the top dot and the LSB the bottom dot. These correspond to pins 1 to

8 or 2 to 9 of the print head, depending on whether the character is an ascender or descender.

Chapter 5 DOWNLOAD CHARACTERS

With this printer you can create new characters and symbols, download their dot data, and have them printed in place of selected characters in the regular character set. Characters that can be generated in this way range from simple but useful symbols like the check mark through complex Chinese or

Japanese characters.

Regular characters are permanently stored in the printer’s ROM, but characters you design are downloaded and stored in RAM for use.

DESIGNING YOUR OWN DRAFT CHARACTERS

Designing and printing your own characters has two requirements: firstly, designing the shape of the character, calculating the data necessary to make the shape, and sending that data to the printer, and secondly, sending the command to print the downloaded characters instead of the regular characters. There are a number of design constraints for download draft quality characters: l

The matrix or grid on which you design the characters is six boxes wide by nine boxes high. l

Horizontally, dots may be centered in a box, ormay straddle a line, making the actual character grid 11 dots wide by 9 dots high. Vertically, dots can only be centered in a box. See Figure 5-l.

Figure 5-l. Dots can be inside boxes or straddle the vertical lines of the grid

The minimum width of a character is five dots. l

The user-defined characters may use eight dots vertically. l

Dots cannot overlap - that is, you may not have a dot inside a box next to one that is on a line. l

You may define any position in the ASCII table, except the block graphics area when you are downloading in the IBM mode.

Photocopy the grid inFigure 5-2 to help design your new characters. We will use a tiny representation of a car-shaped symbol for our example.

128

ASCII Code:

Descender:

Left space:

Last column: m0 = Descender x I28

+ (Left x 16)

+ Last

Figure 5-Z Use this grid (or one similar to it) to define your own draft characters

Defining the attribute data

Before you start the definition, you will need to decide exactly where in the regularASCI1 set you want to place your characters. After downloading, you access your new character by sending the code for the character you replaced.

ml ~13 m5 m7 m9 ml1 m2 m4 m6 m8 ml0

128

724 66 64 76 76 0

0 4 36 2 72

ASCII Code:

Descender: I

Left space: 0

Last column: 77

mO = Descender x 128

+ (Left x 16)

+ Last

Figure 5-3. Add the values of the dots in each column and write the sum of each mlumn at the bottom

Next you must choose whether to make the car symbol an ascender or a descender. This determines how the character is seated on the line:

Ascender: (:;I:&

Descender: C:l I:-:

We decided that our car symbol will not be a “descender”, so a figure “1” is written next to Descender on the grid. If your character is a descender, write a “0” next to Descender.

Next, you must specify the left space and the last print column of the character.

Being able to specify the width of the character allows you to specify the precise area inside the grid that the character will occupy, so that narrow characters will look attractive next to wide ones.

Acceptable values for the left space are 0 to 7, and the last print column are from 4 to 11.

Our character will occupy from column 1 to column 11, so the left space is

0 and the character width data is 11.

Assigning the character data

Now, we calculate the vertical numerical values of the columns of dots, and enter them underneath the grid. For example, looking at Figure 5-3, we see that in the left-most column there are five dots, and they are sitting in the “64” box, “32”box, “16” box, “8” box, and “4”box. Thus its vertical value is 124.

In the next column, there is no dot straddling the vertical line; its value is recorded as 0. define the character, you wiil substitute your value for each of these letters.

Sample program

To demonstrate how to use the download characters, let’s use the “car” character and some other user-defined characters to print a small graph. This program will do just that:

DEFINING YOUR OWN NLQ CHARACTERS

As you probably noticed, NLQ characters are printed by two passes of the print head. Half of the character is printed on the first pass, and the remainder on the second pass. The paper is rolled up half a dot height in between passes to let the print head print dots on the second pass that overlap the previous dots, in order to fill in the spaces and produce denser characters. Addition- ally, the print head speed is halved, and the dots are printed at double the density of draft characters. For this reason, NLQ characters can contain up to 23 dots in the horizontal direction.

Fundamentally, the process to define and print downloaded NLQ character is the same as for draft characters, except that you must supply about four times as much character data, and you must design the character with the two passes of the print head in mind. There are small differences in the way the attribute information is processed also.

In the draft quality mode the attribute byte carries the descender data, and specifies the left space and the character width. In the NLQ mode, the first bit also carries the descender data, and the next three bits describe the character’s left space as with the draft characters, but the last four bits describe the right space. Appropriate allocation of data in these seven bits lets you place the character where you like within the grid, with the restriction that the character must be at least 9 dots wide.

Use the grid in Figure 5-4 to help plot the data. Due to the two-pass process,

NLQ characters can contain up to 16 dots vertically. ml to m23 are the data for the first pass, and m24 to m46 are the data for the second pass.

To make the character data easier to calculate, put the first pass dots inside the boxes on the grid when you are designing your characters, and the second pass dots on the lines. Remember that adjacent dots may not overlap on the same pass; in other words, if one dot is in a box, its adjacent dot on the same pass may not be on a line. Therefore, to make smooth characters, put the dots needed to overlap any spaces in a character in the appropriate places in the second pass grid.

If we plot our car-shaped symbol for NLQ, the grid data will look like Figure

5-5.

The defining process is the same as for draft characters, except that you must select NLQ mode, and you must define 46 data. If you wish to print your

NLQ characters with the regular character set, the remarks regarding the

simultaneous use of regular and download characters in the draft character section apply equally to NLQ characters. ml

Chapter 6 MS-DOS AND YOUR PRINTER

When using your printer with an IBM PC, PC-XT, or PC-AT or compatible, you will probably be using PC-DOS or MS-DOS as an operating system. A number of software tricks may be useful here. This chapter is not, however, a substitute for the operating system manuals supplied with your computer.

To learn how to print files, etc. it is best to read the relevant parts of these manuals.

INSTALLING APPLICATION SOFTWARE WITH

YOUR PRINTER

When installing application software, you may find that your printer is not specifically mentioned in the lists of printers given for installation. How- ever, this should pose no problem. Read this section, and guidelines provided with your software on printer installation.

If you have your printer set up in standard mode, then choose an Epson FX-

10.50 or EX-1000 as your printer to be selected.

If neither of these are mentioned, choose one of the following (in order of preference): Star NR-10/15, Star ND-10/15, Epson FX86e, Epson FX286e.

If you have your printer set up with the DIP switches to emulate an IBM

Proprinter XL, simply choose this from the list of printers available in the application software list.

If the IBM Proprinter XL is not mentioned, use Proprinter II or Proprinter.

If your software package does not mention printers by name, but asks instead what features your printer is capable of, the most common questions are:

“Can your printer perform a backspace?” and “Can it do a hardware form feed?“. You should answer “Yes” to both these questions.

Other software packages may well allow you to install specific features.

Spreadsheet programs will often ask for the maximum number of columns to be printed. This is given below.

Number of columns

Pica

Elite

Condensed pica

Condensed elite

Proportional

CPI

136

163

17.1 233

20 272

Variable

Sometimes the software installation will ask you for an initialization sequence to return to the default settings. The command for your printer is

<ES0 @.

Make sure that the DIP switches are set for the right printer emulation, and that you have selected the appropriate character set using the DIP switches.

If you are in doubt about the configration of your application software, seek expert advice. Your software supplier will probably be your most convenient reference.

EMBEDDING PRINTER COMMANDS

Many word-processors and other software lack commands for changing type style, or printing double-size characters, and some do not even support bold printing or italics. Your printer therefore has commands that can be embedded in documents to control these functions without software help.

The commands consist of a capital letter enclosed in double parentheses, followed by a digit:

Type style (Font):

((F))O

((F))l

m-9)2

W))3 c(P))9

Courier

Sanserif

Orator with small capitals

Orator with lower case

Double width

Double height

Double width and height

Bold:

Italic:

W)O

NW) 1

((I))0

((1)) 1

Non-bold

Bold

Non-italic

Italic

If you want to print a title in double-size Orator with small capitals, then change to regular-size Courier for some text that includes italics, you can use these commands as follows:

File as seen on computer screen:

((F))2

Printer

((S))3

Commands t(F) 10 ((S) )O

Type style,

((1))lanywhere ((1))Oin can and a document. be embedded

Printout:

PRINTER CC~MMANDS

Type style, size, bold print,

Italic

commands can be embedded

anywhere

in a document. and

When you use these commands there are several points to note: l

The type style (0;)) and italic ((I)) commands are ignored if the (m) button was held down when power was switched on. l

The bold command ((B))l gives double-strike printing. In draft mode you may prefer to use emphasized printing, which requires a software command or escape sequence. l

A line consisting of commands alone prints as a blank line. l

Software does not cannot trust your software to give you the correct line width. The printed line may be considerably shorter than the line on the screen; the missing space is the space that was occupied by the commands.

One way to handle the last problem is to prepare your document without the commands, then insert them as a final step, with the margins released. The find, replace, and copy functions of word-processing software can be helpful here.

If you do not use these commands or the panel controls, the printer will print standard-size, draft, non-bold, non-italic characters.

The printer supports various commands in addition to the above, such as quadruple-size printing.

Most of these other commands consist of the escape code followed by one or more letters or numbers.

If your software enables you to place the escape code in your files, or if you were able to define this as a user option during installation, you can also embed these escape sequences.

PROGRAMMING THE PRINTER WITH DOS

COMMANDS

If your system includes the file PRINT.COM you can use the main DOS printing command. Simply type the word PRINT followed by the name of the file you want to print. To print a file named README.DOC, for example, type:

A>PRINT README.DOC

The computer may respond with the following message, asking which printer to use:

Name of list device

IPRNI:

If your computer is connected to only one printer, press RETURN to select the default choice (PRN). Printing will begin and the A> prompt will reappear. You can execute other commands or programs while the file is being printed.

A single PRINT command can print two or more files. List the file names consecutively on the same line, or use wild-card characters (* and ?). Each file will be printed starting on a new page. The PRINT command also has control options. For example, you can terminate a printing job in progress with the /‘I option. (The printer may not stop printing immediately it may have considerable data stored ahead in its buffer.) For the /r option, type:

A>PRINT/T

See your DOS manual for further information about the PRINT command.

If your system does not include PRINT.COM, you can print files by using the PRN device name in COPY or TYPE commands such as the following:

AXOPY README.DOC PRN

A>TYPE README.DOC >PRN

i i

COPY and TYPE do not permit you to execute other commands while the file is printing.

If you want a particular font style, or print pitch, you

make

from the control panel before you start printing. See Chapter 2.

If you print from the DOS command level very often, it will be advantageous to create a printer setup file. Then instead of setting font style etc. manually each time, you can complete the setup with a single command from your computer. For example, you can create a file containing printer commands to select nearletterquality, and select elite pitch. You can find the commands in Chapter 4. We suggest the following: l

Near letter quality l

Elite pitch

<ESC> “x” “1”

<ES0 “!”

<l>

<ESC> “!” cl> is a powerful command that, in addition to selecting elite pitch, cancels unwanted features such as underlining which might be left from previous commands. The angle brackets around the <l> indicate character code 1, which is a control code, not the printable digit “1”.

You may want to place additional commands in this file, such as left and right margins, line spacing and bottom margin commands. Or you may want to create a variety of setup files with a different set of commands in each.

To avoid excess line feeds, you should place the commands on one line in the setup file. You may or may not be able to generate a setup file with word- processing software; it depends on whether your software lets you enter control codes. If your system includes the file EDLIN.COM, however, you can easily create a setup file with the DOS line editor.

An appropriate name for this setup file would be NLQELITE.DAT. To use the DOS line editor, type the command EDLIN NLQELITE.DAT, then type the underlined parts of the following display. Press RETURN at the end of each line. Don’t type the symbol “*“. This symbol means to hold the CTRL key down while pressing the next key: for example, “V means to type CTRL-

V. AC means to type CTRL-C, which indicates the end of the input.

A >EDLIN

New file

81

*V indicates that the following character is a control code. “V[ enters the

<ES0 code. <ESC> has character code 27, and “[” is the 27th character in

ASCII sequence from A. Similarly, “VA enters the control code cl>. See your DOS manual if you need further information about EDLIN.

You can now set up the printer by sending it the file NLQELITEDAT. To avoid unnecessary logging of commands, switch hard-copy output off (by pressing CTRL-PRTSC ifhard copy is on). To print the file README.DOC in NLQ elite type, give the following two commands:

AXOPY NLQELITE.DAT FRN

How the program works

This program begins by assigning a number of printer commands to BASIC string variables (lines 1000 to 1090). You can find most of these commands near the beginning of chapter 4.

The WIDTH “LPTl:” 255 statement in line 1110 means infinite line width.

It prevents the IBM-PC from inserting unwanted carriage returns and line feeds in graphics data.

Actual printing begins in line 1120. Using the preassigned commands, the program prints samples of its different font styles, including a line showing all styles in italics, followed by samples of the print pitches, then some double and quadruple-sized printing.

Next comes the central attraction of the program: a line of text printed fourteen times in expanding and contracting loops to give a barrel effect. The work is done by four printer commands: a command setting the right margin

(line 1400); a centering command (line 1420); a command to vary the line spacing (lines 1440 and 1490); and a command to micro-adjust the space between characters (lines 1450 and 1500).

Next the program returns to normal spacing and gives a demonstration of the printer’s word-processing abilities: bold printing, underlining, subscripts, etc.

The row of automobiles in the next printed line is created by downloading two new character patterns, which are printed in place of the character “c“

(character 60). Details can be found in Chapter 5.

The final part of the program uses dot graphics to print some “SW” logos with various densities. The dot pattern of the logo was originally laid out on graph paper, then converted to the data in lines 2370 to 2600 with the help of a calculator. Each number represents eight vertical dots. (See “Graphics commands” in Chapter 4 for details.)

The pattern is printed in four rows, each eight dots high and 65 dots wide.

Lines 1800 to 1850 read the dot data into a string array variable named

LOGO$. Line 1860 sets the line spacing to 8/72 inch so that the rows will connect vertically. The loop in lines 1870 to 1960 does the printing in four passes of the print head.

Modifications for IBM mode

This program can also be run in IBM mode (DIP switch l-6 OFF) if you change a few of the lines as shown below to allow for difference in some of the commands. You will get a cylinder instead of a barrel effect, becuase the

IBM mode does not have any command to micro-adjust the character spacing.

Chapter 7 TROUBLESHOOTING

AND MAINTENANCE

The following section on troubleshooting and maintenance is intended only as a brief guide to these functions. Remember that your printer is a highly sophisticated electronic device, which also contains high voltage inside. For that reason, only carry out those operations described in this chapter.

CAUTION: Any attempt to carry out operations other than those described here may result in electric shock and/or damage to the printer.

When carrying out any repairs or maintenance, always follow the instructions carefully.

TROUBLESHOOTING

Your printer is a reliable piece of precision machinery, which should not cause you any trouble, provided it is used and treated sensibly. However, the few elementary tips below should avoid you having to make unnecessary service calls. The following table gives you ideas on where to look in this section if you experience faults:

Remember - it is better not to attempt operations or repairs above your level of competence. Otherwise, you run the risk of damaging the printer.

Power supply

If the

POWER

indicator does not illuminate, check the following:

Possible remedy ,

Turn off the printer ensure the power cable is securely connected, and then turn the printer back on.

Turn off the printer, unplug it, and try with another appliance to determine if electricity is being supplied to that outlet.

Check the bottom panel of your printer to ensure that the outlet voltage corresponds to the voltage required by the printer. If they do not match, DO NOT try to operate the printer. Contact your supplier.

Printing

If your printer does not print, or suddenly stops printing, check the following:

Check

Is the interface cable connected securely?

Is the

ON LINE indicator illuminated?

Is the POWER indicator flashing?

Is the paper caught up inter- nally?

Possible remedy

Check both ends of the cable - printer and computer to make sure that the connector is firmly in position.

If itisnot,press thee

ON LINE

Jbutton tosettheprinter on-line.

If it is, the paper has run out. Load more paper.

Is the ribbon caught up around the print head?

Is the software you are using properly installed for your minter?

Can the printer perform self- test operations?

Turn off the power, remove the jammed paper, replace, tumontheprinter, andcontinueprinting.Makesurethat the leading edge of the paper is smooth and uncreased.

Turn off the power, remove the ribbon, retension it, and replace it. This problem occurs most frequently with a worn ribbon, so you may need to replace the ribbon.

Check the installation settings in your software, and reinstall if necessary.

Turn the printer off, and turn it on again, holding down one of the buttons to perform a self-test. If these do not work, contact your dealer.

If the print is faint, or uneven, check the following:

Check

Is the ribbon properly installed?

Is the ribbon worn out?

Possible remedy

Check and reinstall if necessary.

The ribbon has a long life, but evenLually will need replacing. Fit a new ribbon cartridge if necessary.

If dots are missing in the printing, check the following:

Check

Are dots missing at random in the printing?

Possible remedy

The ribbon has become slack. causing it to get caught up. Stop printing, remove the ribbon cartridge, retension and replace it.

The print head is damaged. Stop printing, and contact your supplier for a new print head.

Is a line of dots missing con- sistently throughout the printing?

If your application software cannot print the fonts or characters selected, check the following:

Check

Is your application software properly installed?

Are fonts not being selected properly?

Are characters other than those expected being printed?

Possible remedv

Check the software installation, and re-install the software if necessary.

Check the software installation, and insert the commands necessary for font changes into the software.

Either you are using the wrong International Character

Set (reset with DIP switches or software commands), or you have the wrong character set selected (for example if characters other than IBM block graphic characters are being printed). Correct this with DIP switches or the appropriate software sequences. i

If the printout is not what is expected:

Check

Is the printer installed correctly?

Is the printer not printing anything that you are expect- ing?

Possible remedv

Your software may think that it is driving a different emulation to the one actually set. Check the DIP switch settings to make sure you have the right emulation.

Use the Hex Dump mode to analyze the output from the computer to the printer. This will enable you to determine that the right escape sequences, etc are being transmitted.

Paper feeding

If cut sheet paper (without the ASF) is not feeding smoothly, check the following:

Check

Is the paper release lever pushed back (to the b position)?

Is the paper guide in place and vertical?

Are the left and right guides too close together?

Possible remedy

Set the release lever to the C position.

The paper guide should be in place vertically for cut sheets to feed smoothly.

If the left and right guides are too close together, the paper will not feed smoothly. Move them a little further apart to allow the paper to feed freely.

If it is, then deselect it. Is the ASF selected with the

DIP switch settings?

Are you trying to feed paper using the front panel buttons while the

LINE indicator is illuminated?

Is the paper too thick?

You can only feed paper in this way when the printer is off-line. Set the printer off-line and then feed paper.

Are forms jamming between printing surface and the platen?

There are limits to the thickness of paper that can be fed in thii way. Try with thinner paper.

Clean the surface of the platen roller with a cloth barely dampended with a little alcohol.

If fanfold (continuous) paper is not being fed correctly using the tractor feed, check the following:

Possible remedy

Makesurethereleaseleverispushed to the b position.

Check

Is the paper lever pushed to the & position?

Is the paper guide in the vertical position?

Are the holes on each side of the paper aligned with regard to each other in the sprockets?

Are the sprockets too close or too far apart?

Are the sprockets locked in position and the covers closed?

When using the tractor feed, the paper guide should be horizontal.

If the two sides of the paper are out of alignment, realign them so that the sprocket holes match up.

Misalignment of the sprockets, making the paper too loose or too tight, will prevent a smooth paper feed.

Correct this if necessary.

Check

Is the paper feeding freely into the printer?

Possible remedy

The paper should not be too far from the printer (less than 1 meter/ 3 feet), and there should be no cables or other obstacles obstructing its path. The paper should also be feeding straight into the printer, and an angled feed may cause jams and blockages.

You can only feed paper in this way when the printer is off-line. Set the printer off-line and then feed paper.

Are you trying to feed paper using the front panel buttons whilet.heONLlNEindicatoris illuminated?

Is the paper too thick?

There are limits to the thickness of paper that can be fed in this way (one top copy and two NCR copies). Try with thinner paper.

If the ASF is not operating or is not feeding paper correctly, check the following:

Check

Has the ASF option been selected with the DIP switch?

Is the release lever set to the b position?

Is the ASF correctly mounted?

Is paper caught up neaT the print head?

Are the left and right guides too close together?: -

1 Possible remedy

Select this option

The release lever should be set to the single-sheet position.

Make sure that the ASF is properly seated on the printer.

Stop printing, remove the jammed sheet (you may have to remove the ASF for this), and continue.

If the left and right guides are too close together, the paper will not feed smoothly. Move them a little further

Is there too much paper in the paper feed hopper or stacker?

Was the paper fanned before being fed into the ASF?

Has the paper been used already or is it creased?

Are you trying to feed paper using the front panel buttons whiletheONLlNEindicatoris illuminated?

Is the paper too thick or too thin?

The ASF’s paper feed hopper and stacker can hold 120 sheets each. Make sure that there is no more paper than this in either the hopper or stacker.

If this is not done, paper jams may occur. Remove the stack of paper from the ASF and fan it before reinsert- ing.

Only new, uncreased paper should be used with the

ASF.

You can only feed paper in this way when the printer is off-line. Set the printer off-line and then feed paper.

There are limits to the thickness of paper that can be fed in this way. Try with different paper.

If the paper park facility does not appear to be working correctly, check the following:

Check

Is the paper release lever in the C position?

Has the fanfold paper been properly parked?

Possible remedy

The paper release lever must be set to the & position after the fanfold paper has been parked.

Make sure that the

POWER indicator comes on flashing after the fanfold paper has been parked.

If text is being printed all on one line, or with extra blank lines, check the following:

Check

Is the text all on the same line?

Is text being printed with extra blank lines?

Possible remedy

Carriage returns are not being expanded to

<CR> + <LF> pairs. Check the DIP switch setting and correct.

Two line feeds are being printed. Either make your software print just a carriage return or (if this is not possible), set the AUTO LF to OFF with the DIP switch setting.

If the page length and margins are not what is expected, check the following:

Use the Micro Feed facility to adjust the print position

Use the DIP switch to set up the correct page length, or

MAINTENANCE

Essentially, your printer is a robust piece of equipement, but should be treated with a modicum of care in order to avoid malfunctions. For example: l

Keep your printer in a “comfortable” environment. Roughly speaking, if you are comfortable, then the environment is suitable for your printer, too

(see Chapter 1). l

Do not subject the printer to physical shocks or excessive vibration. l

Avoid over-dusty environments. Dust is the enemy of all precision mechanical devices. l

To clean the exterior of the printer, use a barely damp cloth (use either water with a little detergent or a little alcohol), but do not allow any liquid to fall inside the printer. l

The interior of the printer may be cleaned with a small vacuum cleaner or a compressed-air aerosol (sold for this purpose). When performing this operation, be sure not to bend or damage any cable connections or electronic components.

REPLACING THE PRINT HEAD

This is not a job which you will need to do very often. The print head has been designed to give a life about 100 million characters. In normal everyday use, this will mean years of lift. However, if the print quality is faint, even after I you have changed the ribbon or you have adjusted the gap between the print head and the platen (see Chapter l), the print head will need replacement.

Only use a replacement print head as recommended by your supplier.

1. Turn OFF the printer, and unplug the power cord.

2. Remove the top cover and ribbon cartridge.

3. If the printer has been in operation immediately before this operation, the print head will be hot. Allow time for the print head to cool before attemping to work on it.

4. Move the print head carriage toward the right until you can see the connector cover. Remove the connector cover and pull the cable free from the connector.

5. Unscrew the two screws that hold the print head in place and set them aside.

Figure 7-7. Replacmg the print head

Screws

6. Disengage the cable from the tabs holding it down, then remove the print head.

7. For easy installation of the new print head, move the carriage toward the left end of the rail.

8. Place the new print head on its support, seating it on the two pins.

9. Thread the new cable the same way as the old, securing it under the three tabs on the print head carriage.

10. Plug the cable into the connector, inserting it as far as it will go.

11. Fasten the print head down with the two screws.

12. Move the carriage back toward the right and replace the connector cover.

Slide the connector cover to the left until it locks into place.

13. Replace the ribbon cartridge and top cover, and plug the power cord back in.

chapter 9 CHARACTER SETS

This chapter gives tables of the printer’s standard and IBM character sets.

The decimal character code of each character is shown in an inset to the lower right of the character.

The hexadecimal code can be found by reading the entries at the top and left edges of the table. for example, the character “A” is in column 4 and row 1, so its hexadecimal character code is 4 1. this is equivalent (4 x 16 + 1 = 65) to decimal 65, the number in the inset.

Control codes recognized by this printer are indicated by abbreviations inside pointed brackets.< >.

IBM CHARACTER SET #1

Other characters are identical to character set #2.

The duplication of control codes enables systems with a 7-bit interface to obtain control functions when the most significant bit is set to 1 by the

<ESC> “>” command.

INTERNATIONAL CHARACTER SETS

When an international character set is selected DIP switches 2-2 to 2-4 or by a command from software, the following changes are made in the character set:

U.S.A.

64 91 92 93 94 96 123

124 125 126 155 157

# $ @ [ 1, I ^ - { I } -. t’ Y

See Chapter 3 for the DIP switch settings.

The commands for selecting the international character sets are:

Standard mode: <ES0 “R” n IBM mode: cFS> “R” n

Where n means character code n, i.e. CHR$(n) in BASIC. The values of II are:

0 U.S.A.
