if the student cancels the job at the last page, wouldn't the printer counter still be updated ? if snmp being used, you can still get the latest pagecount from printer even student cancel the last page then you can update student quota base on that. i am not sure how do you know when to update the user quota. maybe when the LPRng doesn't return END of job to the log? am i right?
