The following code is from an example that shows a couple of different methods to print a Microsoft Word document to a PDF file.

At the bottom of this page you will find a zip file with the entire solution for Microsoft Visual Studio 2010.

One of the printing methods used are using printing via Verbs. This is documented in detail here http://msdn.microsoft.com/en-us/library/bb776883.aspx?ppud=4
