c# - How to print PDF on default network printer using GhostScript (gswin32c.exe) shell command

Question

I'd like to print PDF file(s) on windows' network printer via GhostScript.
(I dont want to use Adobe Reader)

I've read gswin32c.exe which can do the job.
I experimented with many commands and coudn't find the way how to force gs to print PDF on my (windows default) network drive.

I don't need point exact network printer- default can be used. But if there is no such option I'm happy to pass printer name as well. (I've tried with param -SDevice="server_IPprinter_name" but this didnt work as well...)

Command working under Windows cmd:

gswin32c -dPrinted -dBATCH -dNOPAUSE -dNOSAFER -q -dNumCopies=1 -sDEVICE=ljet4 -sOutputFile="\spool\Server_NamePrinter_name" "C:est.pdf"

Method created base on above - doesnt work and thorws exception. (Error code = 1)

    /// <summary>
    /// Prints the PDF.
    /// </summary>
    /// <param name="ghostScriptPath">The ghost script path. Eg "C:Program Filesgsgs8.71ingswin32c.exe"</param>
    /// <param name="numberOfCopies">The number of copies.</param>
    /// <param name="printerName">Name of the printer. Eg \server_nameprinter_name</param>
    /// <param name="pdfFileName">Name of the PDF file.</param>
    /// <returns></returns>
    public bool PrintPDF (string ghostScriptPath, int numberOfCopies, string printerName, string pdfFileName) {
        ProcessStartInfo startInfo  = new ProcessStartInfo();
        startInfo.Arguments         = " -dPrinted -dBATCH -dNOPAUSE -dNOSAFER -q -dNumCopies=" + Convert.ToString(numberOfCopies) + " -sDEVICE=ljet4 -sOutputFile="\\spool" + printerName + "" "" + pdfFileName + """;
        startInfo.FileName          = ghostScriptPath; 
        startInfo.UseShellExecute   = false;

        Process process = Process.Start(startInfo);

        return process.ExitCode == 0;
    }

Any idea how to make it working under C#?

I've finally made it working and easy for debugging.
My final method code for those interested:

    /// <summary>
    /// Prints the PDF.
    /// </summary>
    /// <param name="ghostScriptPath">The ghost script path. Eg "C:Program Filesgsgs8.71ingswin32c.exe"</param>
    /// <param name="numberOfCopies">The number of copies.</param>
    /// <param name="printerName">Name of the printer. Eg \server_nameprinter_name</param>
    /// <param name="pdfFileName">Name of the PDF file.</param>
    /// <returns></returns>
    public bool PrintPDF (string ghostScriptPath, int numberOfCopies, string printerName, string pdfFileName) {
        ProcessStartInfo startInfo  = new ProcessStartInfo();
        startInfo.Arguments         = " -dPrinted -dBATCH -dNOPAUSE -dNOSAFER -q -dNumCopies=" + Convert.ToString(numberOfCopies) + " -sDEVICE=ljet4 -sOutputFile="\\spool" + printerName + "" "" + pdfFileName + "" ";
        startInfo.FileName          = ghostScriptPath; 
        startInfo.UseShellExecute = false;

        startInfo.RedirectStandardError = true;
        startInfo.RedirectStandardOutput = true;

        Process process = Process.Start(startInfo);

        Console.WriteLine( process.StandardError.ReadToEnd() + process.StandardOutput.ReadToEnd() );

        process.WaitForExit(30000);
        if (process.HasExited == false) process.Kill();


        return process.ExitCode == 0;
    }
