I need help on something.
Is there a way to know when user click ok button on print dialog box initiated by self.print using PHP? If yes, how? Thanks! If no, thank you for the answer.
This isn't something that would likely be able to be accomplished through PHP. PHP is a server language and the browser doesn't typically send anything to the server when it prints.
You might be able to accomplish this with javascript or a browser plug-in but it would probably be hard to maintain and not work across all browsers.
