Handle is invalid after PrintToPrinter

Question

Hello,
The evironment is a 2008 64 bit server that is used for the crystal report generation in a 32 bit application. The printservers that host the printers are 2003 32 bit servers. The first printserver is connected to the 64 bit 2008 using ThinPrint and from there it connects through to the 2003 printserver with the specific drivers for all printers. If you don't know ThinPrint it 's an application used to shrink the spooled fill for less networktraffic.
We use the redistributable cr2008fp35_redist.zip.
I receive the following error:
Message:The handle is invalid
Source: System.Drawing Stacktrace: at System.Drawing.Printing.StandardPrintController.OnStartPrint(PrintDocument document, PrintEventArgs e) at System.Drawing.Printing.PrintController.Print(PrintDocument document) at System.Drawing.Printing.PrintDocument.Print() at CrystalDecisions.CrystalReports.Engine.FormatEngine.PrintToPrinter(Int32 nCopies, Boolean collated, Int32 startPageN, Int32 endPageN) at CrystalDecisions.CrystalReports.Engine.ReportDocument.PrintToPrinter(Int32 nCopies, Boolean collated, Int32 startPageN, Int32 endPageN)
Kind regards,

Well, we need some baby steps here. I need to be convinced that the printing works in the simplest instance. And that will be a simple win ap, preferably constructed as follows:
1) CR Viewer
2) Two buttons
3) A saved data report
4) Button1 code; CRViewer1.ReportSource = <path to saved data report>
5) Button2 code;
crReportDocument.PrintOptions.PrinterName = "
server\myprinter"
crReportDocument.PrintToPrinter(1, True, 1, 1)
MessageBox.Show("Report finished printing!")
6) Compile
7) Move the app exe to the server
8) Run the app. Test printing from the viewer 1st, then code (button2)
