Deleting completed print queue

Question

I am having a problem deleting the COMPLETED PRINT QUEUE from Preferences Print & Fax. I can delete the Active Queue, but haven't found how to delete the Completed Print Queue. I now have 3 years plus of Completed Print Jobs in the queue, and think some need to be deleted. Need help!

Answer 1

I wish I could give proper credit to whom educated me, but I don't remember who it was. Here is an excerpt of an email thread or discussions post thread that I retained that might be helpful to you:

They aren't stored in a "log" file per se. Each job's control data and status
is stored in /var/spool/cups.

Depending on your needs for log rotation, it might be much easier to just
specify the maximum number of job histories you want to keep. This can be
done via the cupsd.conf (/etc/cups/cupsd.conf) file. Look at about line 218
for:
# MaxJobs: maximum number of jobs to keep in memory (active and completed.)
# Default is 500; the value 0 is used for no limit.
#MaxJobs 500
Alternatively, you could turn off the option for keeping any history at about
line 190:
# PreserveJobHistory: whether or not to preserve the job history after a
# job is completed, cancelled, or stopped. Default is Yes.
So this might give you a clue as to where to start pokin' around...
