How to only print something once

[DaveF]

I have a user pop a window that has a window.print on it. The problem is the
client only wants the coupon printed once. There is no way to stop multiple
prints is there?

If the users have to register to print, you could easily track
it...otherwise you could write a cookie to the client, but that's very
unreliable and easy to hack...no other way.

you could use a captcha control to stop bots from mass printing
(http://dotnetfreak.co.uk/blog/archive/2004/11/06/166.aspx) though that's an
accessibility nightmare...

The problem is the print dialog box that comes up. You can print multiple
coupons.

Oh ya...
well, you might wanna take a look at
http://www.meadroid.com/scriptx/index.asp which provide an ActiveX control
which might help..but other than that, there's no simple solution that I'm
aware of.
