Not sure if I fully understand you... but if you 
set 

   PreserveJobFiles Yes
   PreserveJobHistory Yes

in cupsd.conf, your job files will be preserved as
/var/spool/cups/d-NNNNNN files, where "NNNNNN" is
the job ID. Combine these settings with

   MaxJobs XYZ
   MaxJobsPerUser XYZ
   MaxJobsPerPrinter XYZ
   MaxPrinterHistory XYZ
   AutoPurgeJobs Yes|No

to set up some kind of automatic deletion of older 
jobs.

Cheers,
