Are there ways to ensure printing only occurs once?

[Eric Layman]

Hi,

If an E-coupon is limited to one person, are there ways to prevent it from
printing more than once?
Since on the print dialog, user can print multiple copies.

You shouldn't be attempting to prevent the coupon from being printed more than once.

What you should be focusing on is preventing
a coupon from being *redeemed* more than once.

True. There is no way of preventing more than one printing because it is
very easy to do a File -> Save As and then print as many copies as you'd
like. Even clever methods like using Active X collapse in the way of Print
Screen

Or even:
1) User prints coupon using <hideously complex system to prevent user
printing more than once>
2) User takes print out to a halfway decent photocopier (so that
copies are indistinguishable from original)
3) Profit
