3.

Q. What is the Epson ESC/P 2 command set?

A. As the leading impact printer vendor, the Epson Standard Codes for

Printers (ESC/P) has become a de facto standard for most dot matrix printers. Epson Standard Codes are featured by most other vendors as an immediate entry into a wide range of third party software. As the market continues to develop new requirements, Epson has moved to improve its standard by offering a version called ESC/P 2.

4.

Q. What are the benefits of ESC/P 2?

A. The features of ESC/P 2 are divided into two categories: Scalable Fonts, and Enhanced Graphics.

SCALABLE FONTS: ESC/P 2 provided access to Scalable Roman and

Sans Serif fonts. The Scalable Fonts are available in even increments from 8 to 32 points. In addition to these sizes, 10.5 and 21 point sizes are also available. Epson printers with ESC/P 2 perform the calculations necessary to scale the fonts. The Scalable Fonts are most easily selected within application software programs that provide ESC/P 2 printer drivers.

ENHANCED GRAPHICS: ESC/P 2 also provides Enhanced Graphics capabilities in certain software applications supporting the raster graphics mode of ESC/P 2. Enhanced Graphics is defined as a finer, more accurate placement of printed dots leading to greater clarity of text and sharper more detailed graphics in graphical printing environments such as

Microsoft Windows or Lotus 1-2-3. Enhanced Graphics also allows for true 360 horizontal DPI printing with a single pass of the print head, creating better print quality and faster print speeds than other dot-matrix printers.

5.

Q. When printing multi-page documents, what would cause the AP-3250 to print the first page correctly but print too low on the following pages?

A. This difference in print position is easy to adjust in most software application programs. Most application programs have a default page length of 66 lines per page when using 11" continuous paper. Since the

AP-3250 uses single sheets of paper, it automatically provides a small top and bottom margin. Since these margins are non-printable area, the AP-

3250’s maximum number of lines per page when using 11” singe sheet paper is 61 lines. Most software application programs include an option to

PSB No: P-0084A

Page: 3 of 6 adjust the maximum number of lines per page. Decreasing the program’s maximum number of lines per page by 5 (e.g. 61 lines) should correct for this print position difference.

6.

Q. Why is a ON-LINE/OFF-LINE or PAUSE button not present on the

AP-3250’s front panel?

A. The AP-3250 printer was designed to be as easy to use as possible.

Because of this, the AP-3250 was designed any unnecessary buttons.

The AP-3250 automatically goes into a ready condition after being powered on. (See the question below for additional information.)

7.

Q. Why does the AP-3250 produce two (2) long and two (2) short beeps when first power-on?

A. The AP-3250 produces these beeps at power-on to indicate that it has completed its power-on initialization process and is ready to print.

8.

Q. What are the product codes for AP-3250 options and supplies?

A. Listed below are the product codes for the AP-3250 optional push tractor and ribbon cartridge.

S015032

C800262

Fabric Ribbon Cartridge

Push Tractor

9.

Q. What is the advantage of purchasing an optional Push Tractor?

A. The optional Push Tractor allows the AP-3250 to use continuous narrow carriage paper while still maintaining the ability to use the AP-3250’s builtin single sheet paper cassette. When using the optional push tractor, the

AP-3250 can accept a two part carbonless multi-part form with a total thickness up to 0.18mm.

10.

Q. What interface does the AP-3250 come standard with?

A. The AP-3250 comes standard with a built-in Centronics compatible parallel interface.

14. Q. Does the AP-3250 use DIP switches?

A. No, the AP-3250 does not use DIP switches. The various features settings are selected through use of the two buttons on the printer’s front panel.

15.

Q. Can the AP-3250 print on labels?

A. Yes, the AP-3250 can print on labels. The optional pull tractor is used to load continuous labels.

16.

Q. Can the AP-3250 print on envelopes?

A. Yes, the AP-3250 can print on envelopes. The envelopes are loaded at the rear of the printer by using the printer’s manual insertion slot. (Note:

The printer must be placed in the upright position first.)

17.

Q. Can the AP-3250 print on legal size paper?

A. Yes, the AP-3250 can print on legal paper. Legal size paper is loaded at the rear of the printer by using the printer’s manual insertion slot. (Note:

The printer must be placed in the upright position first.)

18.

Q. The AP-3250’s User’s Guide lists information on 120, 220 and 240 volt versions of this printer. How can I purchase a 220 or 240 volt version of this printer?

A. The AP-3250 is available only in the 120 volt configuration in the U.S.A..

19.

Q. Can the AP-3250 print in landscape orientation?

A. Yes, but the AP-3250 requires the use of a software application program because landscape characters are not included in its built-in characters set. Two very popular software application programs for printing in the landscape mode are Sideways and Always.

2 0 .

Q. Why is the AP-3250’s parallel cable connector located on the side of the printer instead of the rear like most other printers?

A. Since the AP-3250 may be operated in two different positions it was necessary to relocate the parallel cable connector to the side of the printer.

21.

Q. Can different fonts be selected on the AP-3250’s front panel?

A. Yes, different fonts may be selected from the AP-3250’s front panel by using the font button. However, all font selections made from the front panel can be overridden by an software application program. The recommended method to select fonts is through the program that you are using to print. If the program does not provide font selection abilities, then the printer’s font panel is very useful.

22.

Q. When printing high density (360 x 360 DPI) bit-image graphics why does ink smearing sometimes occur on the outside edges of the printout with certain print patterns?

A. The AP-3250 builds the graphic image by making multiple passes when printing high density graphics. Dependant upon the printed pattern and the ink absorption factor of the paper being used, ink smearing may occur on the edges of the printed pattern. This occurrence is much less noticeable when printing at resolutions lower than 360 x 360 DPI. Should this phenomenon be encountered, select a lower graphic resolution in your software program.

ESC X m n1 n2 (Select Pitch and Point Size)

C X m n1 n2 is the command for selecting pitch and point size where m, n1 and n2 are variables. The variable "m" is used to select the pitch which is the character spacing. The variable "n1" selects the point size and the variable “n2”, at this time, will always be 0 (zero). The variables "m" and "n1" are explained below.

The values used for ’m’ are 0,1,18,21,24,30,36,42,48,60, and 72. If "0" is used as the value for ”m”, there will be no change in pitch. If "1" is used as the value for "m", the character pitch will be proportional spacing. To determine the character pitch for all other values of "m", divide 360 by "m". For example, if m=60 then 360 divided by 60 equals 6 and the character pitch is 6 characters per inch. If m=30, the character pitch is 12 characters per inch.

For the Roman and Sans Serif fonts, the values used for "n1" are 0,16,20,21,24,

28,32,36,40,42,44,48,52,56,60 and 84. For all other fonts, the values used for

"n1" are 0,21, and 42. The actual point size that will print is n1 divided by 2. For example, if n1=20, the point size is 10. If n1=48, the point size is 24. NOTE:

When selecting a point size larger than 24 (the value for n1 is greater than 48) select proportional spacing (m=1) for the character pitch.

In the Basic programming language, the command would look like this.

LPRlNT CHR$(27);"X";CHR$(1);CHR$(48);CHR$(0);”This is 24 point proportional spaced”

Chr$(27) is ESC, chr$(1) selects proportional spacing, chr$(48) selects 24 point character size. At this time, n2 is always zero (0).

Line 20 - computes the value for “n1” in the ESC X command.

tine 21 - check to ensure that a valid point size was input If the point size is valid, the program jumps to line 30. If the point size is not valid, the program prints a message on the screen and starts over again.

Line 30 - computes the value for “n1” for advancing paper using the ESC ( v command.

Line 40 - sends the “Set Pitch and Point Size” command to the printer. (Note: The pitch is set for proportional spacing for all point sizes to ensure proper character spacing regardless of the point size.)

Line 50 - sends the “Set Relative Vertical Position” command to the printer. This command advances the paper in preparation for printing the next line.

Line 60 causes the program to start again at the beginning.

NOTE: To halt the program, hold down the “Ctrl” key and press the “C” key.

ESC ( C m1 m2 n1 n2 (Set Page Length in Defined Units

ESC ( C m1 m2 n1 n2 is the command for setting the page length in units where ml, m2, n1 and n2 are variables. The “unit’ is usually 1/360 of an inch unless defined otherwise by the “ESC ( U" command. Currently, the values for m1 and m2 MUST be m1=2 and m2=0.

To determine the values for n1 and n2 perform the following steps.

1.

Determine the desired page length in inches.

2 Multiply the page length by 360.

3.

Divide the result by 256 using long division.

4.

The remainder in the quotient from step 3 is the value for n1.

5.

The whole number in the quotient from step 3 is the value for n2.

EXAMPLE

1.

The page length is 8.5 inches.

2 8.5 x 360 = 3060

3.

3060 divided by 256 = 11 with a remainder of 244.

4.

n1=244

5.

n2=11

In the Basic programming language, the command would look like this.

This command, as listed in the line above, will set the page length to 8.5 inches.

NOTE: The current line becomes the top of form. This command cancels any previously set top and bottom margin settings. If you wish to set the top and bottom margins via software command, the commands must be issued AFTER the “Set Page

Length in Defined Units” command. The proper page length setting can be confirmed by issuing a “Form Feed” command, chr$(12), or by pressing the “FF button on the control panel while the printer is “Off Line”.

ESC ( v m1 m2 n1 n2 (Set Relative Vertical Position

ESC (v m1 m2 n1 n2 is the command for advancing the print position vertically in units where m1, m2, n1 and n2 are variables. The "unit" is usually 1/360 of an inch unless defined otherwise by the “ESC ( U" command. Currently, the values for ml and m2 MUST be m1=2 and m2=0.

To determine the values for n1 and n2 perform the following steps.

1.

Determine the desired vertical motion distance in inches.

2 Multiply the distance by 360.

3.

Divide the result by 256 using long division.

4.

The remainder in the quotient from step 3 is the value for n1.

5.

The whole number in the quotient from step 3 is the value for n2

EXAMPLE

1.

The desired distance is 1 inch.

2 1 x 3 6 0 = 3 6 0

3.

360 divided by 256=1 with a remainder of 104.

4.

n1=104

5.

n2=1

In the Basic programming language, the command would look like this.

This command, as listed in the line above, will feed the paper up 1 inch from the current line. The current print column (horizontal position) IS NOT changed.

‘Reverse” paper feed less than 1/2 inch can be performed with this command. To accomplish "reverse" paper feeding requires the following steps.

1.

Determine the desired vertical motion dice in inches.

2 Multiply the distance by 360.

3.

Divide the result by 256 using long division.

4.

Subtract the remainder in the quotient computed in step 3 from 256.

5.

The result from step 4 is the value for n1.

6.

The value for n2 will always be 255.

ESC ( t n1 n2 d1 d2 d3 (Assign Character Table)

ESC (t n1 n2 d1 d2 d3 is the command for assigning character tables where n1, n2, d1,d2, and d3 are variables. Currently, variables, n1, n2 and d3 MUST be n1=3, n2=0, and d3=0. Variable d1 is a number corresponding to one of the four tables selectable with the ESC t n command. This is the table that will be replaced. Valid values for d1 are 0,1,2, and 3 (see Table 1 below). Variable d2 is a number corresponding to a registered table. This is the table that will replace the table indicated by Variable d1. Valid Values for d2 are 0, 1,3,7,8, and 9 (see Table 2 below).

Table 1

Table 2

After using the ESC ( t command, the ESC t n command MUST be sent to select the table before printing from the new table. For example, the command ESC ( t 3 0 1 3

0 is sent (assign Registered Table 3 (PC850) to Selectable Table 1 (PC437). In order to print the character (ASCII 245), the command ESC t 1 must be sent. In the Basic programming language, the sequence would be as follows:

LPRINT CHR$(27);“(T);CHR$(3);CHR$(0);CHR$(1);CHR$(3);CHR$(0);

LPRINT CHR$(27);"t";CHR$(1);

LPRINT CHR$(245)

Some ESC/P2 documentation may illustrate as many as 22 different Registered

Tables. The Registered Tables are a part of the character set, therefore, they are contained in the Character Generator ROM. The CG ROM differs based upon the destination country. For this reason, only the above Registered Tables are available on LQ-570, LQ-1070, LQ-870 and LQ-1170 printers sold for the U.S. market. Foreign

Character Generator ROMs ARE NOT available in the United States. The following

Send the Select Character Table command to the printer selecting Selectable

Table number 0 as the current Character Table for printing.

If the Registered Character Table number is 0, do not execute commands in lines

70 through 90. This is because the Italic Character Table duplicates control codes and non-displayable characters in ASCII values 127 through 160. Program lines 100 and 110 prevent the attempted printing of this range of ASCII values.

Note: tines 70 through 90 will execute ONLY if the Registered Character Table to be printed is NOT table number 0. Refer to the conditional command in line 60.

70 If the Registered Character Table number is not 0, send the Print Data as

Characters command to the printer. Specifically, this command, as listed, tells the printer to print the next 31 bytes as data, not control codes.

T O determine the values for n1 and n2 perform the following steps.

1. Determine how many ASCII codes will be sent sequentially immediately following n1 and n2

2 Using long division, divide the quantity of ASCII codes that will be sent sequentially immediately following n1 and n2 by 255.

3. The remainder in the quotient is the value for n1.

4. The whole number in the quotient is the value for n2

EXAMPLE

1. The symbols for the different suits of a card deck (hearts, diamonds, clubs, and spades and are to be printed. These are each separate

ASCII codes (ASCII codes 2, 3, 4, and 5 when using the PC437 Character table).

2. 4 divided by 255= 0 with a remainder of 4.

3 . n 1 = 4

4 . n 2 = 0
