Printer accounting and cutoff from UNIX: is it possible?

[Alexander Verbraeck]

At our department (information systems) a large number of students
are working on Unix systems (Sun, HP). These systems are connected 
via ethernet. On the system we have a number of laser printers. At
the moment, students are wasting enormous amounts of paper using the
laser printers. We would like to limit their use of the printers.

Unix does accounting for the printers. Question: is it possible to
check for the number of printed pages and perform a "budget cutoff" 
when the allowed number of pages is surpassed? Does anyone have
software for this? 

BTW: Why does UNIX have a cutoff for disk usage (quota) but not for 
printer usage?

Any help would be appreciated!
Sincerely,
