onbeforeprint() and onafterprint() equivalent for non IE browsers

Question

I want to send some info back to my database when a user prints a certain web page. I can do this in IE with onbeforeprint() and onafterprint() bu

Answer 1

I think that it's simply not possible to this properly. Or at least - not with any technology I know nor with any of the answers given previously.

Both using onafterprint and using serverside dynamic-image-generating script would tell you that the page was printed even when the visitor merely went to print preview mode and then canceled out.

However, I would like to learn how to get the proper information, so that I can be sure that page was actually printed.
