Meanwhile (1998-08-20) a software project exists, that tries to provide support for the deskjet series of printers 720/820/1000 under Linux. All other GDI printers cannot be used under Linux up to now.
All necessary software packages for the above mentioned Deskjets are available
for testing as either updates or new versions on the S.u.S.E. FTP-Server :
You need at least version 1.3 of (S.u.S.E.-)aps
(see also
new_aps.html). Furthermore you need pbm2ppa
(package "ppa
"); Both are included in version 5.3 of S.u.S.E. Linux .
Here's the location where you can download the packages :
You can install RPM packages with YaST (see handbook) or directly with rpm
(see pakete_manuell.html).
Sofar we don't know, if reliable result can be achieved using the package ppa
.
Unfortunately we don't have all of the necessary hardware for testing purposes.
Feedback welcome !
See http://www.rpi.edu/~normat/technical/ppa/ for further information.
pbm2ppa
(package "ppa
"):
As was said above, at least apsfilter S.u.S.E. 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 (weniger wäre besser, aber dann blinkt es) bottom -100 left 250 right 250
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 S.u.S.E. .
We would like to thank Clemens Dorda <Clemens.Dorda@studbox.uni-stuttgart.de> for feedback and in-depth information.
There's also a patch for Ghostscript 3.33 for the Brother HL 720; Unfortunately this driver wasn;t included in recent versions of Ghostscript .
