LEXMARK 7000 PRINTER DRIVER FOR LINUX
(AND OTHER OPEN SOURCE SYSTEMS)
(C) 1999 Henryk Paluch
paluch@bimbo.fjfi.cvut.cz
March 28, 1999
PROGRAM RELEASE: 990328
Hi folks!
This is my fifth release of Lexmark 7000 driver for Linux. The most
important change is preliminary COLOR support.
MANY PARTS OF THE DRIVER WERE REWRITTEN TO ACHIEVE COLOR SUPPORT. THIS
VERSION MAY CONTAIN NEW BUGS (EVEN FOR BLACK PRINTING). USE ON YOUR OWN RISK!
Lexmark does NOT provide protocol specification for third party. They consider
it "copyrighted". So, this work is completely based on disassembling printing
files (using driver for Windows and Print to File capability in programs). It
does mean, that this program comes WITHOUT ANY WARRANTY! Use it on your own
risk only!
This release is not "Plug & Play". Read the instructions carefully.
1. CURRENT FEATURES
o Black/White printing 600x600 dpi (if you need 600x300d dpi, use older 990207
revision, please)
o Preliminary 600x600 dpi colour printing in CMY mode (currently does not uti-
lize black) - tested on Lexmark 7000
o work as filter PBM -> printer, e. g. easy integration with Ghost-Script
o available under GNU GPL license including source code
o script for easy integration into RedHat's printing system
o support for Lexmark 5700
o from 990321 relase should not crash, when printing large amount of black
pixels :-)
2. SUPPORTED PRINTERS
The table below shows experience of Lexmark users with my driver. Pay
attention to column 'WORKS'.
Model Works Notes
-----------------------------------------------------------------
Lexmark 7200 YES reported by Dan Davis
Lexmark 7000 YES reported by Nigel Lock and myself :-)
Lexmark 5700 YES reported by Brian Wainscott and others.
Lexmark 3200 NO reported by Chris Davis
Lexmark 1100 NO reported by Ben Adler. The protocol seems
to be very different. I'll need tons of
luck to have success
I'm curious to see report on Lexmark 5000 and others that use the same
12A1970 cartridge. Any heros there? Please report your experience to inform
other users of that printers.
3. FILES
File Description
--------------------------------------------------------------------
Makefile project Makefile
README this file
lexmarkprotocol.txt description of "top secret" protocol
pbm2l7k.c the Lexmark 7000 driver (works as filter)
pr5700.prn initialization (prologue) for Lexmark 5700
pr7000.prn initialization (prologue) for Lexmark 7000

stairsb.prn Black & White stairs for Lexmark 7000
stairsc.prn Colour stairs for Lexmark 7000
4. INSTALLATION
4.1. Compilation
Simply type
$ make
It should compile pbm2l7k.c into pbm2l7k binary. Works "out of the box" at
least on RedHat 5.2
4.2. Integration into RedHat's printing system
(1) Backup your existing file /usr/lib/rhs/rhs-printfilters/ps-to-
printer.fpi
(2) Copy these files into /usr/lib/rhs/rhs-printfilters/
# cp pbm2l7k pr*.prn ps-to-printer.fpi \
/usr/lib/rhs/rhs-printfilters
(3) Owners of Lexmark 5700 need to add `-m 1' to change driver mode to Lex-
mark 5700 instead of default - Lexmark 7000. See
# ./pbm2l7k -h
for more information. It does mean that you should manualy add this
switch in ps-to-printer.fpi and psprint script, if you have Lexmark
5700.
(4) Configure at least one printing entry in /etc/printcap. You may use Red-
Hat printing tool. Just select any *NON* PostScript printer you wish
(PCL DeskJet or LaserJet). Printer selection and resolution is overriden
to Lexmark in my ps-to-printer.fpi script. Do *NOT* check `Fast text
printing', otherwise text printing will not work.
(5) Set correct paper size. Add either `-sPAPERSIZE=a4' or `-sPAPERSIZE=let-
ter' to gs command in psprint and ps-to-print.fpi scipts.
(6) If you want print in color, you need to create little pipe using my PNM-
raw to PBMraw CMY(K) converter:
./pnmraw2cmyk < pnmrawbitmap.pnm | ./pbm2l7k -c > /dev/lp0
-c means print in color (it assumes 3 PBMraw bitmaps for CMY colours on
input). You should brigthen the image (for example using pnmgamma pro-
gram). See `pscprint' script for example. Note that pnmraw2cmyk is
quite slow, due dithering of large color bitmap.
(7) Cross fingers and try to print some file :-)
4.3. Manual printing of Post-Script files
See psprint and pscprint scripts, how to do it (the former is for black
and later for colour printing).
5. NOTES
As I stated above, this driver is *pre-pre-pre-pre ALPHA* version. Use
it on your own risk. I'll gladly appreciate bug reports and bug fixes
concerning this driver. I also hope, that Lexmark will change his "OSS
deny" policy soon.
The most recent version of this driver should be available on:
http://bimbo.fjfi.cvut.cz/~paluch/l7kdriver/
ftp://metalab.unc.edu/pub/Linux/hardware/drivers/lexmark7000*.tar.gz
I hope you will enjoy this "underground" release of Lexmark 7000 printer
driver

6. THANKS
I'd like to thanks to many people for feedback and help to make the driver
to work on additional Lexmark models. The list comes in chronological & chaotic
order:
Dithering routines were ripped from print-util.c - part of GIMP package. That
file was written by Michael Sweet (mike@easysw.com)
7200 series:
Dan Davis - thanks for report, and notice about docs
7000 series:
Nigel Lock - thanks for report, and notice about unclear point in installation
docs.
5700 series:
Stephen Vinall, Peter Mott, Brian Wainscott, Javier Munoz, Phil Humpherys for
feedback and help.
1100 series:
Ben Adler - thanks for reports and nice test patterns.
I apologize if someone is missing. I have little chaos in my mailbox ;-)
