Silently Print

[qqw1943]

hello.
i am a new c# learner.
when i try to print a pdf file using the example below:

using (GhostscriptProcessor processor = new GhostscriptProcessor())
           {
               List<string> switches = new List<string>();
               switches.Add("-empty");
               switches.Add("-dPrinted");
               switches.Add("-dBATCH");
               switches.Add("-dNOPAUSE");
               switches.Add("-dNOSAFER");
               switches.Add("-dNumCopies=1");
               switches.Add("-sDEVICE=mswinpr2");
               switches.Add("-sOutputFile=%printer%" + printerName);
               switches.Add("-f");
               switches.Add(inputFile);

               processor.StartProcessing(switches.ToArray(), null);
           }

there's always a dialog (see pic in attach files).
but i need a Silently Print,which means no dialog is needed
can i get some help here ? thank you.

Hi ist late, but maybe it still helps.

The Pirntername has spaces!

Try to use
switches.Add("-sOutputFile=\"%printer%" + printerName + "\"" );

What is the printer name at your local.
This code worked well at my side.

switches.Add("-sDEVICE=mswinpr2");
switches.Add("-sOutputFile=%printer%" + "Microsoft Print to PDF");

Thanks.
