title: Before print event in Visio Interop
body: <p>I'm using the Visio interop in C#. I'm creating an application which set up watermark into visio document. I need to add a specific watermark when visio document is printing, but visio has no event like "Document_BeforePrint" in MS Word. Now I can only handle the CTRL+P key pressing, but it's not enough, cause users print document using "Menu -> Printing". Is it possible to handle this action?</p>
