Prevent user printing multiple copies!
Posted on 2003-02-21
Is there any way to prevent users from printing multiple copies?
(Maybe there is a registry entry to disable the option 'Multiple Copies' of the printing dialog.)
Short project description:
We want to charge the student for her/his printed pages. Therefore we are monitoring each printer queue.
But if someone prints multiple copies, the print queue doesn't show it, that is, the student could print 100 copies and would only have to pay 1 copy.
Here are test results with different applications:
MS Winword and MS Access (1 copy vs. n copies):
The number of pages is in both cases the same only the size in the queue changes.
MS Outlook, MS Internet Explorer, MS Notepad, Adobe Photoshop, (1 copy vs. n copies):
The number of pages and the size in the printer queue are in both cases the same.
This is the only program (of the tested ones) which is "correct" in the printer queue. It creates for each copy it's own printing job, that is, for n copies there are n printing job in the queue.
Thank you for every hint.
