The first thing you need to do is pick your model, some people
- use absolute monthly quotas
- allow students to print to a queue but require a teacher to allow each
print job -- cups can do this out of the box.
- some other variant.
I have to admit I've never used quotas, though I have had print jobs queued
Queueing print jobs for approval can be done by adding this line:
Option job-hold-until indefinite
to the stanza for a given printer in /etc/cups/printers.conf. You then
restart cups (system->administration->services) and jobs should start
queuing. To approve jobs, someone in the cupsys group must login to the
cups webpage on the server
and look under "jobs".
This page seems to describe a simple way to do quotas:
although if you need more, the PyKota quota add-on for CUPS provides more
powerful quota systems for CUPS.
The Common Unix Printing System (CUPS) documentation is here:
To get the most out of CUPS you may need to be willing to carefully edit
config files in /etc/cups/ as some of the graphical configuration tools
don't support all of the features.
