- In addition to the original package described below,
- this archive includes two new routines:
-
- fhprtsc.com is a bug fix for hprtsc.com so that
- it will drive an Epson FX-80 type printer. The new routine,
- fhprtsc.com, functions just like the original hprtsc.com.
-
- Also included is a routine, nhprtsc.com, which does not
- wait for the page number to be input. Instead, it just
- automatically dumps graphics page 1 when PrtSc is pressed.
- Included also are the modified assembly routines, commented
- to indicate where the changes were made. This routine comes
- with absolutely no guarantee of any kind.

- This program implements a graphics screen dump from a
- Hercules monochrome graphics board. It was written for the
- Epson LX80/LX90 printers, but it should work on other Epson
- compatible printers.
-
- To load the program, simply type HPRTSC from the DOS prompt.
- This should probably be done in your AUTOEXEC.BAT file. From
- then on you simply need to press the PrtSc key (it is
- shifted) to print out a screen image.
-
- When the PrtSc key is pressed, HPRTSC checks to see if the
- Hercules board is in text mode or graphics mode. If it is in
- text mode, the screen is dumped to your printer as normal
- ASCII characters. In graphics mode, HPRTSC will pause and
- wait for you to press either the '1' or the '2' key to
- indicate which of the two graphics pages on the Hercules
- board you wish to dump (if you don't understand this, press
- '1'; if that doesn't do what you want, press PrtSc again and
- then try '2'). If you press any key other than '1' or '2',
- HPRTSC will beep and then return. You can use this to freeze
- an animated graphics display to look at it more closely.
- Just press PrtSc to freeze the screen. To unfreeze it, just
- press any key other than '1' or '2'.
-
- More detailed comments appear at the beginning of the source
- code which is included with this package.
