HPPRINT (c) 1987, GMUtant Software

HPPRINT.EXE is a short 'C' program to print out source code listings
on an HP-THINKJET printer. The program prints in compressed mode
with 80 lines per page. You should use the Alternate Mode on your
printer (for IBM-PC). With minor modifications, this can drive
most any dot-matrix printer...just find out what your codes for
compressed print and 8 lines per page are and modify.

Here's the source code for HPPRINT

/*
** Program: hpprint.c
** Function: file dump program for HP-THINKJET.
** Prints program in condensed mode, 8 lines to inch (80 lines page)
** Line Numbering optional.
** Date: 09/14/87
** Compiler: Microsoft, version 4.0
** Author: W. Grotophorst, Library Systems Office, George Mason U.
