This is an example command of how root would set a print quota in CUPS, assuming an existing printer named
lpadmin -p quotaprinter -o job-quota-period=604800 \
-o job-k-limit=1024 -o job-page-limit=100
This would limit every single user to print no more than 100 pages or 1024 KB of
data (whichever comes first) within the last 604,800 seconds ( = 1 week).
