Events to determine when a WebBrowser object has finished printing?

Question

I'm very new to C# and have written a small app that I intend to call from a larger c++ app. Anyway, this small c# app simply takes a URL and prints it once it has loaded, this works fine. However my problem is that, once printed, I want the app to close, but there is no event or status returned from the print calls on the "System.Windows.Forms.WebBrowser" object.

Does anyone know how I can determine if something is in the print queue? Or failing that, does anyone have any ideas of other ways to solve this problem?

Thanks in advance for any help!
