Presently (1998-08-20) there is a software project underway, which is trying to provide support for the deskjet series of printers 720/820/1000 and the Lexmark printer (model 7000) under Linux. All other GDI printers are currently not supported by SuSE Linux.
The necessary software packages for Deskjets have been included with SuSE Linux since version 5.3;
Please make sure that in addition to Ghostscript, the packages "aps
" and "ppa
" are installed on your system.
We presently cannot vouch for the complete reliability the ppa
packet, as the availability of
hardware for more thorough testing is presently not available to us. Your feedback is always welcome!
Additional information is obtainable from the web site: http://www.rpi.edu/~normat/technical/ppa/ . Before contacting the author we do strongly recommend that you read the following FAQ: http://www.rpi.edu/~normat/technical/ppa/faq.html
pbm2ppa
(package "ppa
"):
As previously mentioned, at least apsfilter SuSE version 1.3
is required.
/var/lib/apsfilter/SETUP
and choose one of the following devices (according
to your printer) :
/dev/lp1
, /dev/lp2
or /dev/lp0
for the printer device; choose "mono
" (color is not supported up to now) and the desired paper size
(e.g. "a4
").
Ghostscript uses "pbm
" (portable bitmap format) for the Device; the program
pbm2ppa
is used as a post-processor in order to convert the data flow
to the "ppa
" protocol (printer performance architecture).
For these reasons the area that should be printed should be optimized even if Ghostscript uses the
specified paper size. The program pbmtpg
is used for this purpose together with pbm2ppa
:
pbmtpg | pbm2ppa | lpr -Praw
pbm2ppa.conf.hp1000
, pbm2ppa.conf.hp720
or
pbm2ppa.conf.hp820
from the directory /usr/doc/packages/pbm2ppa
to
/etc/pbm2ppa.conf
*and* adjust the offsets. This is necessary in order to
optimize the result of the printing process.
Further information can be found in the original file CALIBRATION
.
In case you're using the 720C, the following values lead to usable results :
xoff 75 yoff -500 top 0 bottom 0 left 150 right 150
In case of the 820Cse the following values lead to usable results :
xoff 25 yoff -325 top 100 (less would be better, but that causes blinking) bottom -100 left 250 right 250
These values work for the 820 Cxi:
xoff 0 # \ Adjust these for your printer yoff -325 # / (see CALIBRATE) top 0 bottom 0 left 120 right 160
Tip: Choose at least 1 cm margin on both sides in applications.
lpr
as usual. The filtering
is then done by the apsfilter
that was adapted by SuSE.
We would like to thank Clemens Dorda <Clemens.Dorda@studbox.uni-stuttgart.de> and <Thies.Freymuth@lrz.tu-muenchen.de> for feedback and in-depth information.
Information on model 5700 can be found at: http://www.ultranet.com/~setaylor/papers.htm.
Information on an alpha driver for the 7000 model con be found at: http://bimbo.fjfi.cvut.cz/~paluch/l7kdriver/
We presently cannot vouch for the complete reliability the above referenced information.
For the Brother HL 720, HL 730 and compatible models, there is the driver "hl7x0
" for Ghostscript.
Many thanks to Pablo Saratxaga and Ralf Mayer for their input on this.
