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
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.

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.
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 built-
in 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.
PSB No: P-0084A

20.
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).

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.
