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.
How you can tie these information through jobs ?
You add an estimation, then the job abort. On the 'next' job you must check if any
before has aborted ?
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.
You're lucky, or maybe we are italian .... :-))

Subject: LPRng: Accounting Related Question
Dear list,
i've upgraded to the latest release, hoping that helps, but my
accounting problem was not solved.... Let's me explain....
I need to update the accounting information about print jobs in
'real-time' into a mysql DB, to implement a real-time quota check for
our students in the cs-labs. Almost all the things are fine, so I can
check the print quota and manage to print or not, but the problem is
about the aborting of a job. Using the ifhp accounting I can get the
printing status from the printer into the fileend line, but if I start a
job of 500 pages, then at 490 pages I send a job abort, the fileend will
not be raised, so I loose the only chance to bill the user for that
print job. The solution in the manual (see the next job start and count
the difference....) is not reasonable for a 'real-time' check, I believe
it's too complex to implement (or I'm wrong ?).
Someone has solved this, or there is a workaround ?
Tks in advance.
