Use, instead "Window.Print()" Method. Hope it helps u. Sorry, it will work only for the Web Application. And if ur application is an web app then use it in onclick event of any button. It will work.

I am using windows application. Problem is that I don't know if that is really a convertable type..you know from printdocument to string or stringbuilder

So I would really need help...That is the last thing in my project to do.
