RedMon - Redirection Port Monitor

Transparent PostScript printing from Windows.


The RedMon port monitor redirects a special printer port to a program. RedMon is commonly used with Ghostscript and a non-PostScript printer to emulate a PostScript printer. RedMon can be used with Ghostscript as a PDF creator.

RedMon can be used with any program that accepts data on standard input.

Using RedMon you create a redirected printer port. If you connect a Windows printer driver to the redirected printer port, all data sent to the redirected port will be forwarded by RedMon to the standard input of a program. The output of this program can be sent to different printer port, or the program can generate whatever output it desires.

The RedMon online help is available in English.
