During the printing process, two temporary files are created. These files are named according to their job-number.
For instance, if a print job was the 150th print job submitted on the computer system, the temporary files would include the number "150".
In this example of the 150th print job on the system, two temporary files of importance are:
/usr/spool/lp/requests/150-0 /usr/spool/lp/temp/150-0
