My experiences of printer quotas can be found at

In a GUI application, that matches our experience.   If you print from a 
command line, you get an error message which hints that your quota has been

AFAIK CUPS cannot set different quotas per group.  What we do is setup an 
alias for each of our printers, and only allow access to this alias by the 
staff group.  This lets staff print as much as they like, and students are 
limited to 7 pages per day.

Pykota lets you setup printer quotas on an individual user of group basis and 
also can notify users when there quota is about to run out.  I tried to get 
this working, but I encountered problems with the PostgreSQL database 
configuration.  It might be simpler with an LDAP or MySQL database.  There is 
a link to the Pykota homepage on the above wiki page.
