I'm trying to print XPS documents from a windows service on the .net framework. Since Microsoft does not support printing by using System.Drawing.Printing nor by using System.Printing (WPF), I'm using the native XPSPrint API. This is suggested to me by Aspose in http://www.aspose.com/documentation/.net-components/aspose.words-for-.net/howto-print-a-document-on-a-server-via-the-xpsprint-api.html.
When I try to print an XPS document from a windows service, the result contains strange characters instead of the text I want.
I tried with different printers (including virtual printers like for instance PDFCreator), different users and user-privileges for the service, different xps generators (aspose, word 2007, word 2010), different platforms (windows 7, windows 2008 R2) but all have the same result.
Does anybody knows how to solve this? Any help would be appreciated!
For those who want to try it, I shared some files via:

- document.xps: the XPS document to print
- document_printed_to_pdfcreator.pdf: the printed document that demonstrates what is going wrong
- XpsPrintTest.zip: a sample VS2010 solution with the sample code
The sample code for the managed windows service is:

using System.Data;

using System.ServiceProcess;
using System.Text;
