--- Comment #17 from Zdenek Dohnal zdohnal@redhat.com --- The file which goes from 'lp' to cupsd scheduler and which is going into texttopaps filter is in /var/spool/cups. It begins with 'd', has job id in its filename and ends with number of files in the job.
f.e. file for job id 1, which has one file to print, is d00001-001.
