Introduction
Section
Your dot-matrix printer is an easy-to-use desktop printer that provides lowcost, high-quality output from your personal computer. It handles cut forms,
document-on-demand, and continuous form applications.
Your printer is a wire-matrix printer. The printer makes impressions by forcing
a hardened wire against an ink ribbon to transfer ink to the paper on impact. A
dot is printed each time the wire strikes the ribbon against the paper. This
impact printing technology has unique capabilities. The information in this
manual enables you to fully use the capabilities of dot-matrix impact printing.
This book applies to the Lexmark Forms Printer 2400 Series dot-matrix family
of printers. Differences that occur between printer models are noted.
The information in this manual is intended primarily for hardware and
software programmers, engineers, technicians, and others who require indepth technical information. If you need information to operate your printer,
see your User’s Guide.

Printhead Description
Your printer uses dot-matrix impact technology to generate characters. The 248x
has a 9-wire printhead. The 249x has a 24-wire printhead.
248x
The 248x printhead has nine wires arranged in a single vertical column. The
diameter of each wire is 0.30 mm (0.012 in.). The center-to-center distance
between wires is 0.353 mm (1/72 in.). The printhead has an impact force
sufficient to generate readable copies on multipart forms and envelopes up to
and including 6-ply forms (original plus 5 copies).
249x
The 249x printhead has twenty-four wires arranged in two parallel vertical
columns of twelve wires each. The diameter of each wire is 0.22 mm (0.009 in.).
The wires in each of the rows are vertically separated to produce a 0.141 mm (1/
180 in.) space between the centers of adjacent dots. The printhead has an impact
force sufficient to generate readable copies on multipart forms and envelopes
up to and including 4-ply forms (original plus 3 copies).
Section 1: Introduction
9
Printhead Movement
The printhead moves by a direct-current stepper motor.
The printhead can print while moving in both directions (bidirectional print).
When the printhead is printing in both directions, it automatically finds the
shortest path to print the next line.
The maximum velocity of the printhead is 1117.6 mm (44 in.) per second for the
248x and 1041.4 mm (41 in.) per second for the 249x.

Diagnostics
This section discusses diagnostics at power-on and how to do the printer test.
Power-On Diagnostics
The following tests are performed when the printer is turned On.
• RAM Test
• Font ROM/Microcode Sum Test
• Timer/Interrupt Controller Test
• NVRAM Test
• Switch Scan Test of the operator panel
• Carrier Initialization
• Paper Feed Initialization
If any errors occur during the tests, a combination of blinking LEDs indicate
which test failed.
Printer Test
You can run a Printer Test to aid in problem determination. In addition to the
normal power-on internal tests (see “Power-On Diagnostics” on page 15), the
printer test generates a sample printout.
This test printout can be printed either with or without connecting the printer to
your computer.
Section 1: Introduction
15
To run the printer test, follow these steps:
Make sure the paper and ribbon are installed.
1
Turn the printer Off.
2
Press Line Feed while you turn the printer On.
3
After a few seconds, release Line Feed.
4
To stop or interrupt the printer test:
Press Start/Stop. The test stops after a complete line of characters has
1
printed.
Press Start/Stop to continue the printer test.

Programming Examples
Examples in this manual have been formatted to be processed by a simple
BASIC program. The BASIC program reads an input file and writes data to an
output file. Printer commands may be entered into the input file in a
hexadecimal format and enclosed with opening and closing delimiters.
The opening delimiter is a less-than symbol, ’<’, followed by an ’x’. The ’x’ may
be either upper or lower case. The closing delimiter is a greater-than symbol,
’>’.
Within the delimiters, hexadecimal data must be presented in two-digit pairs.
White space, blanks, carriage returns and line feeds may be used between the
pairs. In addition, a comment may be added to the end of a line by using a
minus sign, ’-’, at the start of the comment. All data after a minus sign is ignored
until a carriage return or line feed is encountered.
The example format used in this book is shown below:
<x
1B36
1B5B0400000001B5
1B5B640100A0
1B5B4905000055007801
>
All of the examples use this encoding method and have been tested using the
following BASIC program:
1000 INPUT "Enter file name to be printed"; FILENAME$
1010 OPEN FILENAME$ FOR INPUT AS #1
1020 OPEN "prtrout.bin" FOR OUTPUT AS #2

parameter changes, if any, and store in working RAM and all
macros. It also sets the default macro to Disable.

IBM Emulation Mode Printer Commands
This section provides a detailed description of IBM emulation mode
commands you can use with your printer.
Control Codes
Control codes are one-character printer commands that are used to:
• Manage the printing of a job.
• Control the movement of the cursor, which changes the current print
position.
• Control primary and secondary font selection.
The first 32 characters of the Standard ASCII table are control codes. This
printer uses the following control codes.

Advances the paper to the top of the next
page and does a carriage return.

Data
CR Moves the current print position to the left
margin of the current line.
SO Prints all characters in double-width
mode.
SI Condenses printing from 10 characters per
inch (cpi) to 17.1 and 12 cpi to 20.
DC1 Selects the printer. 17 11
DC2 Returns condensed printing to normal (10
cpi)
DC3 Signals the printer to stop accepting data
from the computer. This control code has
no effect on the parallel interface.
DC4 Cancels double-width printing mode and
returns printing to normal.
CAN Clears current line buffer of data already
received to print on the current line since
last Form Feed, Line Feed, Carrier Return,
or Cancel.

Space SP
Moves the print position one character
space to the right.
Escape Sequences
An escape sequence (two or more characters of information) lets you change the
way the printer is currently printing. Like a control code, it gives you control
over the printed output. The escape sequence begins with the character ESC
(decimal 027, hexadecimal 1B). The printer recognizes this character as the
beginning of a printer command signalling that the information that follows is
control information and not data to be printed.
Printer Command Parameters
A command parameter sets the value for a command. This value stays constant
until either a different value resets the command or a command resets the
printer to its default values. For example, after the printer receives a command
32 20
28
Section 3: IBM Emulation Mode Printer Commands
that selects a right margin beginning at column 63, the right margin of each
printed page begins at column 63. The margin remains constant until a right
margin command with a different value resets the margin, or the printer is reset.
In this section, command parameters are indicated by a lowercase n. Usage
Notes explain how to compute this parameter.
Command Structure
The printer commands use ASCII; the decimal and hexadecimal digits are
shown for your convenience.
Most commands have the following structure (spaces have been added for
readability; do not include spaces when you type the command):
ESC & a n C data
& Parameterized character from ASCII table range 33-47 decimal.
a Group character from ASCII table range 96-126 decimal that
specifies a group type of control.
n Value within specified numeric range, from ASCII table range
48-57, 45, 46 decimal. If a value is not specified, a value of 0
is assumed.
C Termination character fr om ASCII table range 64-90
(47-122 w/chaining) decimal.
data Binary 8-bit data (from graphics, and so on). The value field
specifies the number of bytes of binary data.

Example of IBM Emulation Mode Printer Command
Select Code Page (
(A short description of the command follows)
This command placed before the first character changes the active code page.
(The printer command format follows with the decimal and hexadecimal values).
Format ESC [ T 4 0 0 0 Hc Lc
Decimal 27 91 84 4 0 0 0 Hc Lc
Hex 1B 5B 54 04 00 00 00 Hc Lc
name of command
)
Usage Notes
The digits 4 0 0 0 (decimal), 04 00 00 00 (hexadecimal) are constants.
To calculate Hc Lc for a code page that is not shown:
• Divide the code page number, such as 437, by 256.
— The whole number result is the Hc value.
— The remainder is the Lc value.
• If your code page has an alphabetic character, such as 437G, add 10,000 to
the code page number, then divide by 256.
• Code page information begins on page 188.
Related commands list other commands that can or should be used with the
printer command being described.
Usage Notes give additional information for that command, such as:
• how the command reacts with other commands
• any other command that is required, or that supplements the command
• how the datastream is affected by the command
Pay attention to the uppercase (capital letter) and the lowercase letters. If the
format shows an uppercase letter, enter the command with an uppercase letter.
If the letter in the command format is lowercase, enter it as lowercase. The
printer looks at the uppercase and lowercase letters as separate command
instructions.
The uppercase letter O is different from the numeral 0 (zero). Notice that the
uppercase O is wider and rounder than the zero. To help you with this distinction, the text that describes the command shows the numeral 0 and also spells
out zero.
