The problem seems to be of the parallel port printing. The backend is
not able to pass the data on to the printer through the parallel port.
All filters work correctly, but the backend does not succeed to write
data. It says
D [25/Oct/2010:13:39:30 +0200] [Job 15] Read 8192 bytes of print data...
in the error_log and then no more log message of the job appears,
especially no "Wrote 8192 bytes of print data...". Seeems that then the
backend is waiting infinitely for the printer accepting the data.
A possible workaround is to print via network or USB.
Can you run the following command
ls -l /dev/lp* /dev/parport*
and post the output here? Can you also attach your /var/log/syslog after
a failed attempt to print? If there are messages containing "audit", try
also to deactivate AppArmor with
sudo aa-complain cupsd
Does this solve the problem?
If you still cannot print, can you try to print after running the
following commands:
chown lp.lp /dev/lp* /dev/parport*
chmod 660 /dev/lp* /dev/parport*
Does this help?
