Exceptions when Printing with WPF (GDIExporter)

The same (?) problem was also reported in much greater detail two years ago here: http://social.msdn.microsoft.com/Forums/en-US/windowsxps/thread/ec26f3a1-5ceb-4f0e-8ba3-74a5ade98a9a/#fbae1d9f-2dcf-4d45-98a7-c7aa8f016271

We are developing a mind mapping application (www.novamind.com) using C# and WPF (.NET Framework 4.0) 

Some of our customers seem unable to print from our application. Based on the exceptions this seems to be a problem with the framework. I don't know how to get around or solve this problem and would appreciate any input.

These two exceptions seem to be the most common errors:

--

Exception : System.Printing.PrintSystemException
