Redmon postscript output

Question

I'm using the redmon to redirect de output postcript my c# .exe to process. The print configuration is the same as if I'd do to configure the ghostscript, but instead of the ghost path I informed my .exe path.

To convert the postscript in PDF I'm using the ghostscript, as the code bellow

Stream content = Console.OpenStandardInput();
using BinaryReader standardInputReader = new BinaryReader(content);

using (FileStream standardInputFile = new FileStream(psFile, FileMode.Create, FileAccess.ReadWrite))
{
    standardInputReader.BaseStream.CopyTo(standardInputFile);
}
standardInputReader.Close();

string ghostScriptPath = @"C:\gs\gs9.52\bin\gswin64.exe";

String ars = @"-Ic:\gs\gs925\lib -dNOPAUSE -dBATCH -q -dSAFER -sDEVICE=pdfwrite -sOutputFile=teste.pdf psFile.ps";
Process proc = new Process();
proc.StartInfo.FileName = ghostScriptPath;
proc.StartInfo.Arguments = ars;
proc.StartInfo.CreateNoWindow = true;
proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
proc.Start();
proc.WaitForExit();

But the ghostscript always throws the error %%[ Error: undefined; OffendingCommand: Redmon ]%%.

If I use the ghostscript instead of my program everything works fine, but if I "intercept", the error always happens. I logged the output on the two cases, but the log is the same, a piece bellow.

The full log can be seen here

OK well if you look at the file you posted it begins:

RedMon - Redirection Port Monitor
Copyright (C) 1997-2012, Ghostgum Software Pty Ltd.  All Rights Reserved.

REDMON WritePort: about to write 4096 bytes to port.
%!PS-Adobe-3.0

Everything up to the %!PS-Adobe is not PostScript and is not being sent by the printer driver. That's all being sent by the RedMon Port Monitor. The output then ends with:

%%EOF

REDMON WritePort: OK  count=2489 written=2489
REDMON EndDocPort: starting

REDMON WriteThread: ending
%%[Page: 1]%%
%%[LastPage]%%
REDMON EndDocPort: process finished after 1 second

REDMON EndDocPort: 0 bytes written to printer
REDMON EndDocPort: ending

and there everything following the %%EOF is not PostScript and is coming from the Port Monitor. Since all of that doesn't form a valid PostScript program, sending it to Ghostscript will cause an error of some kind.

You need to work out how to strip that verbiage out and only send the PostScript language program to Ghostscript.

I'm afraid I can't help you with that, I don't know how your application is receiving data from RedMon.

In any event this isn't really a Ghostscript, or PostScript, question.
