HPSREAD.ME - Written by Allen Sparks, 1/31/91

This readme file belongs with files of the name HPPS*.*

HPPS stands for Hewlett-Packard Print Screen.  It is a 
terminate and stay resident (TSR) program, written in assembly
language, which allows a user to use the "Print Screen" key 
to print the contents of graphics and text screens on an
HP-compatible printer.  The utility is invoked by typing
"HPPS", followed by the optional parameters "/R", and/or "/2".
The utility will then stay in memory and print the screen to 
an HP printer whenever the Print-Screen key is pressed.
See the files HPPS.DOC, and HPPS.ASM for specific information.

I have recently modified this utility to work correctly on
EGA systems in 16 color 640x350 mode (mode 10h).  I did this 
at the request of Evan Englund of the EPA Exposure Assessment
Division in Las Vegas, so that this utility may be 
distributed with Geo-EAS. Note that the file HPPS.DOC indicates 
HPPS.COM may be freely distributed, when accompanied by HPPS.DOC.

The files which should be distributed with Geo-EAS are: 

        HPPS.DOC, HPPS.COM, and HPSREAD.ME

Direct any questions about this to me at (702) 597-4124.

NOTES: 

     This utility will work with CGA and EGA Graphics Cards ONLY!!

     If you use it with a non-HP compatible printer, be prepared to
     waste volumes of paper printed with gibberish!  

     I have only tested it with EGA mode 16.

     I modified this program with Geo-EAS in mind, which I know
     only uses the EGA in mode 16, and the CGA in B/W 640x200 mode.
     Therefore, I haven't considered how it might behave in other
     applications, such as CGA 320x200 4-color mode.  In such a 
     situation, it is possible that colors other than white will 
     not printed. It is probably not a problem, since EGA is so
     popular now, and few people will need to use these other modes.
