Hi,

> Is there a Windows event that I can bind to that will tell me what the user did (print or cancel).

That's unlikely, even an undocumented one. The easiest way to prompt the user for a printer is the PrintDlg function. This functions returns true or false, depending on whether the user hit OK or Cancel. It's never posted back to the browser as a message, but a simple return value that can't be intercepted. All customization is done through a window procedure that is called directly everytime a message is sent.

If you need more control, you have to prompt the user and then find a way to print using the selected printer..
