I would like to know if there is a way to set a Nevron Diagram Document so that in print, and print preview, it's centered into the page.

I've tryed with Nevron Diagram "VB.NET Examples \ Printing \ Print Manager" example. When I select "size to content" the Diagram is centered on my video. But when I go in "Print Preview" it isn't in center of printing page.

Thank you
