Have a look at both. I just tried apsfilter, went through the apsfilterconfig script and when I try to test print I got an error. You can see the error in the apsfilter.log attached file (where it says tubería rota it translates to broken pipe). Anyway, I purged apsfilter and tried magicfilter. Ran magicfilterconfig --force: Printer name Short name Spool dirDevice Input filter --- XeroX DocuPri xerox /var/spool/lpd/xerox /dev/lp0 ljet4l * I created the xerox/ directory for spooling (shouldn't I change the group owner to lp instead of root?); Perhaps, but I think it should work as it is. From the list of filters it gave me, I chose the default one (ljet4l). I know this is not a laserjet, but I don't know which one to try, as there was none close to cdj550, which is the one I found supports these xerox models: Xerox Document Homecentre Xerox DocuPrint C5 C6 Xerox Workcentre 450cp Xerox xj6c it is called dj550c in magicfilter. ljet4l probably won't work. The resulting /etc/printcap looks like: lp|xerox|XeroX DocuPrint C15:\ :lp=/dev/lp0:sd=/var/spool/lpd/xerox:\ :sh:pw#80:pl#72:px#1440:mx#0:\ :if=/etc/magicfilter/ljet4l-filter:\ :af=/var/log/lp-acct:lf=/var/log/lp-errs: [...] This is not woking the same now: $ lpq lpq: lp0: unknown printer also: [...] $ lpc status lp: queuing is enabled printing is enabled no entries no daemon present which should mean that the lpd daemon is not active? $ ps aux ... root 2548 0.0 0.4 1444 596 ? S12:21 0:00 /usr/sbin/lpd from the unknown printer error above I suspect you have set the PRINTER environment variable to lp0 ?. With your printcap entry, this is wrong. One of export PRINTER=lp export PRINTER=xerox export PRINTER=XeroX DocuPrint C15 or, since lp is the default anyway, unset PRINTER would work. Noone except lpd ever wants to know to which interface (say: kernel device) your printer is attached, and lpd can read it off from printcap. Everyone else just needs to know the name (or one of the names) of the correct printcap entry and this name is what lpr's -P option expects. This may have been the problem with apsfilter, too, but the error message isn't very informative. broken pipe usually means that one of the (many) programs in the chain in which the printer data is passed on has died unexpectedly. [...] Does that mean your Xerox is HP DeskJet compatible? If so, both magicfilter and apsfilter will work. I don't know. I just called to the customer service and asked them what driver they use. They couldn't tell me and they'll have a tech to call me back. If the dj550c/cdj550 driver works then it is compatible to a DeskJet 550 Color. As to your question about ghostscript: yes, the Aladdin version should be newer. Aladdin releases older versions under the GPL after some time, these become GNU ghostscript. On the other hand, GNU ghostscript is free software, and (therefore :) the GNU release may contain bugfixes and additions committed by third parties and not found in Aladdin releases.

Hello Horacio, printing under linux is achieved by the cooperation of different pieces of software. The general picture is as follows: kernel: the only thing it knows about printing is how to squeeze bytes through a parallel port in a way (protocol) a printer can receive them. The kernel doesn't know what those bytes mean or how to tell the printer what to do with them. A user or program can take advantage of this kernel feature by writing data to one of the /dev/lp* devices. Most (not all) printers interpret the bytes they receive as plain text and print them in a fixed width font unless special control bytes are sent. Try a ls /dev/lp0 command and see what happens. lpr/lpd: * writes data to devices in the right order for printing (so two users/programs trying to print at the same time will get their two documents intead of one big mess). * can optionally transform your data into something meaningful for your printing hardware by invoking so-called printing filters (see below) before it gets printed. These are not part of the lpr package, you have to supply them. * Is usually sufficient to print plain text in the default font, but by itself doesn't know how to address the better features (graphics, nice fonts, etc.) of any given printer. A printcap entry associates a collection of configuration data (/dev/lp* device, filters to use, spool directory and other nifty stuff) with one or more friendly names. This is what lpr calls a printer. The printer names can be chosen totally arbitrary. The only exception is that if you don't specify a printer to lpr, it assumes you mean printer lp. Thus, one of the names of the most frequently used printer should be lp. printing filters: look at the data they're given, determine the data format (PostScript, jpeg image, man page, etc.) and try to translate it into the language (e.g. PCL for HP LaserJet or ESC/P for Epson dot matrix printers) some specific printing hardware understands. Most filters will in turn use other programs like ghostscript for substantial parts of the work they have to do. The Debian distro contains at least two printing filter packages, magicfilter and apsfilter, both containing filters for a collection of different printer models. Their respective configuration scripts will ask you some questions and then create a suitable printcap entry for you. Personally, I prefer magicfilter, but the important question is not taste but whether one of the packages contains a filter that will translate into a language your Xerox DocuPrint knows. Have a look at both. The printer is recognized, as advertised by the relevant parts of dmesg: parport0: PC-style at 0x378 [SPP,ECP,ECPEPP,ECPPS2] parport0: detected irq 7; use procfs to enable interrupt-driven operation. parport0: Printer, Xerox DocuPrint C15 Recognized is a bit too much. The message just means the thing wired to the first parallel port has identified itself as a printer called Xerox DocuPrint C15. lp0: using parport0 (polling). So the right device to send bytes to the printer is /dev/lp0 I had lpr installed, and have just installed several other programs (Aladdin Ghostscript). Then went to read the relevant howtos, but I can't see it clear enough. I've tried to print a postscript file from 'gv', and also tried a simpler 'man man | col -b | lpr', but all I get is those jobs in the spool: $ lpq waiting for lp to become ready (offline ?)

According to the howtos this should be set as: PRINTER=printer_name; export PRINTER Shouldn't be necessary if you have only one printer. Just call the printcap entry lp. Ah, but what's printer_name? Is it perhaps that I have to make a symlink in /dev/ to /dev/lp0 (say, /dev/xerox - /dev/lp0), and then: PRINTER=xerox; export PRINTER or? No. Also, I didn't apply any changes to /etc/printcap, so the only uncommented lines are: lp|Generic dot-matrix printer entry:\ :lp=/dev/lp1:\ ^^^ If you change this to lp0, you may at least be able to print plain text. There is nothing connected to lp1 (most likely you don't have a lp1 at all) so lpd cannot get the data sent out.

Re: How to print? (Xerox DocuPrint C15)
Erm one thing I noticed reading that was the first half made reference to lp0, whereas the printcap referes to lp1.
