SPRINT: Speedy PRINT replacement for IBM ROM BIOS routines.
= =====
Ver 1.0 - 11/04/84 by Ward Christensen
PURPOSE:
- To make screen print MUCH faster than the BIOS ROM routine under most
conditions by suppressing trailing blanks from the print lines.
- To have an execution-time option to eject the page after the print.
- To translate unprintable control characters shown on the screen, to '.' so
the printer won't "mess up". (Prompted by Phoenix PFIX debugger which places
04H characters on the screen to represent unprintable characters in its ASCII
dump)
- To simulate an IBM printer box graphics when printing on a Gemini 10-X
printer.
INSTALLATION:
- Simply type: SPRINT, or place it in your AUTOEXEC.BAT.
DEPENDENCIES:
- Uses BIOS ROM int 17h for printer output, and INT 10h to get the characters
off the screen.
- Must be installed BEFORE GRAF or GRAPHICS or other routines that assume INT
5 is the default screen-print routine.
OPERATION:
- Left-Shift-PrtSc will print the screen, but NOT form-feed after print.
- Right-Shift-PrtSc will print the screen and form-feed after print.
COPYRIGHT:
- I do not place any conditions upon this program. HOWEVER, This code is a
"derivitive work" based upon the Copyrighted IBM BIOS screen print code, and
thus is thus COPYRIGHT (C) IBM Corp.
NOTES:
- The GEMINI translation is assembly-time optioned. Users with a standard IBM
printer will appreciate the speed improvement and form-feed option.
- Jams itself into screen print INT 5, ignores what was there.
