Need help with CUPS
 

I've installed cups from source but it does not want to print at all. I've got an HP DeskJet 710c wich is not supported so I got the .ppd file and already copied it to the ./cups/model directory and installed the correct printer. So the printer is ready, accepting jobs on /dev/lp0 (it's the only parallel port linux told me is configured) but when I type 'lpr afile' it does nothing. The hp is setted as default printer. Even typing 'lpr -P HP710 afile' (HP710 is the printer's name) it does nothing.
The 'lpq' command tells me that the hp710 is ready and printing (after sending a job) but it is not; and after a while the job vaporizes.
If anyone knows what can I do then I would be very greateful. Thanks in advance.

Adding some facts..
 

Sorry, I forgot to include a couple of facts:

* Linux Red Hat 6.0 running Kernel 2.2.5-15.

* What's up at the '/var/log/cups/error_log' file?

typing a 'lpr afile' command the error_log file shows:

-------------------------------------------------

job 36 queued on 'hp710' by 'root'.

started filter /usr/lib/cups/filters/textID 1032) for job 36

started filter /usr/lib/cups/filters/pstops (PID 1033) for job 36

started filter /usr/lib/cups/filters/cupsomatics (PID 1034) for job 36

started backend /usr/lib/cups/backend/parallel (PID 1035) for job 36

PID 1034 stopped with status 2!

-------------------------------------------------
Is the problem `cupsomatics'?


* The web interface administrator tells me:

-------------------------------------------------
printer state: idle, accepting jobs. (sometimes: 'stopped accepting jobs')
------------------------------------------------
