What we've done is the following:
- use software to estimate the # of pages printed (yes, i know it's bad
and easily fooled)
- debit the student's account for the amount estimated (cancel the job if
insufficient balance)
- reconcile the hardware count to the estimation and flag for manual
inspection if the difference is more than 1 or 2 pages.
In the rare case that someone aborts the job, they've already been charged
the estimated cost. Their account is adjusted with the difference
between what was actually printed and the estimate after the next
print job raises the flag.
We rarely have problems with students trying to cheat the system.
Most of the jobs that we end up inspecting are cases where the printer has
crashed or jammed.
