Mac OS X Server 10.3: Maximum number of print jobs, and how to change it
Summary
If you need to know the maximum number of print jobs that may be processed simultaneously, or how to change or remove the limit, then you're in the right place.
Products Affected
Mac OS X Server 10.3
The maximum jobs per queue is controlled by the /etc/cups/cupsd.conf file. The default setting is 500 jobs per queue. You can change that setting by editing the MaxJobs entry in cupsd.conf:
#
# 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
For your change to take effect, you must uncomment the "MaxJobs 500" line by removing the number sign (#). The new setting will take effect when you restart the server.
Practical and theoretical limits
The factor that ultimately limits the number of print jobs is the amount of free hard disk space on the server's startup volume. There is no theoretical limit, but you may encounter a practical limit if the server's startup volume does not have adequate space for the MaxJobs setting that you have chosen.
Note: The CUPS print queue only supports storage of print files on startup volumes.
