This is an example command of how root would set a print quota in CUPS, assuming an existing printer named “quotaprinter”:

root# 

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).
