If the system has some non-real printers like XPS, or "print to PDF" then such printers will be count  by the "PrinterJob.lookupPrintServices()" so no exception will be thrown and the test just hands suggestion the user to save the printed document somewhere. The hang occur exactly where it is reported in JBS "WPrinterJob._startDoc".

I'm not sure we can avoid this if user selects "print to pdf" as default printservice or if it is the only printservice available. Maybe converting it to manual is the way to go.
