A DOS VDM could not actually access the hardware.
I would set up a print under OS/2 to 'talk' to LPT1. Then I could set up a
virtual printer, the same as real one, aimed at LPT2, and then re-direct the
LPT2 output to LPT1.
The DOS program thought that it was talking to LPT2, as it was actually
dealing with the re-direction code.
The same thing can be done under Windows with a program called RedMon, so
that you can 'print' to Ghostscript and get PDF output.
My question.
How do you re-direct output from a virtual port to a real printer spool,
under Fedora?
Are you thinking of something like this?

Summary : Extension for creating pdf-Files with CUPS
Description :
"cups-pdf" is a backend script for use with CUPS - the "Common UNIX
Printing System" (see more for CUPS under http://www.cups.org/).
"cups-pdf" uses the ghostscript pdfwrite device to produce PDF Files.
This version has been modified to store the PDF files on the Desktop of
the user. This behavior can be changed by editing the configuration file.

Well that's part of the idea. I have a DOS program (accounting) which
can only write out to LPT1, LPT2 or to a file. The latter is a pain. I
used to use redirection to divert the output which the program thought
it was sending to LPT2, to a networked printer.
I'm looking for something to do the same thing under Fedora 5. The link
you point to, does the first portion (redirection) but appears to be
tied to piping the input into ghostscript's pdfwriter.
What I am looking for is the Linux equivalent of the Windows program
REDMON (which does the first bit.)
