A program which will work for many cases to do what you want is very
easy to write. If the program whose output you wish to grab is doing
its printer output via DOS services (i.e., not using BIOS or going
direct to the hardware) all you gotta do (in C) is to redirect the
output which would go to "stdprn" to somewhere else instead:

   #include <stdio.h>

   FILE * printer_file;

   printer_file = freopen ("prtfile.dat", "wb", stdprn);

   system (your_program);

   fclose (printer_file);

   exit(0);

This will grab all of DOS's output to the printer and write it to a file
named "prtfile.dat" (w/o the quotes).

As to whether or not your application is bypassing DOS or not, the easiest
way to find out is to try this and see if it works. If not, all you've
lost is about 20 minutes!
