Often there are questions regarding print quotas where Samba users (that is, Windows clients) should not be able to print beyond a certain number of pages or data volume per day, week, or month. This feature is dependent on the real print subsystem you're using. Samba's part is always to receive the job files from the clients (filtered or unfiltered) and hand them over to this printing subsystem.

Of course one could hack things with one's own scripts. But then there is CUPS. CUPS supports quotas that can be based on the size of jobs or on the number of pages or both, and can span any time period you want.
