There is another setting which does indirectly influence your ability to keep your printed jobs:

    MaxJobs 500

This tells CUPS to keep 500 jobs at most (current and past combined). The oldest jobs are deleted first to keep the total beneath that limit; if the 500 are all new jobs (not printed yet), the 501st one will be rejected...

(And look also at the related "MaxJobsPerPrinter" and "MaxJobsPerUser" settings).

> The "PreserveJobHistory On" keeps the cXXXXX ("control") files in /var/spool/cups/. With the cXXXXX there, your web interface can display the list of past jobs:  http://localhost:23631/jobs?which_jobs=completed (and, BTW, utilities like KDEPrint's kjobviewer also need these CXXXX files to display the job history).

The actual print file as received by CUPS are in the dXXXXX ("data") files (in the original format, before any conversion by CUPS filters). The default "PreserveJobFiles Off" directive makes CUPS delete the dXXXXX files after their print is completed.
