Probles with CUPS Hanging Up Frequently

[Aaron E.]

This will fix it, add to cupsd.conf..

MaxJobsPerPrinter 300
PreserveJobHistory No # Files that start with cxxxxxxx
PreserveJobFiles No # Files that start with dxxxxxxxx

The problem is the directory filling up and never purging. You can 
change the MaxJobsPerPrinter to what you need, I have 300 due to an app 
sending multiple print jobs at any given time. That was overkill but it 
keeps the jobs from piling up and locking up cups if a print queue breaks..

He also deleted all the files in /var/spool/cups/tmp and then restarts CUPS before anyone is able to print. Can some one please explain this to me?
