- This program is a TSR (memory resident) utility that adds
- more capabilities to the DOS print screen functions. DOS
- by itself, will handle the text modes, but if the CGA graphics
- modes need to be dumped to the printer, then GRAPHICS.COM
- must be loaded. There is a severe limitation to GRAPHICS.COM's
- capabilites and that is, that it will not work on EGA graphics
- modes, that is the following modes;
-
- 320x200 - 16 color (mode d)
- 640x200 - 16 color (mode e)
- 640x350 monochrome (mode f)
- 640x350 - 16 color (mode 10)
-
- EGADUMP should be loaded AFTER graphics.com, since graphics.com
- will try to handle these modes if it gets control before
- EGADUMP. In order to be able to dump all screen modes to the
- printer, GRAPHICS.COM (or CGRAPHIC.COM) must be loaded
- in addition to EGADUMP.
-
- EGADUMP is set up to work with the IBM graphics printer, which
- means that if you have a printer that has an EPSON or IBM mode,
- EGADUMP will work with it. If your print screen works now in
- graphics mode, then it will work with EGADUMP.
-
-
- There are two printer strings used in EGADUMP;
-
- ESC,"L",n - set up for double density graphics
- ESC,"3",n - set to n/216" linefeeds
-
-
- Command line switches:
-
- The /I switch given when EGADUMP is loaded
- will cause black to be printed as black and white
- to be printed as white. The default for EGADUMP
- and GRAPHICS.COM is to reverse black and white
- when printing. The switch can be invoked as follows;
-
- EGADUMP /I
-
- The /F switch given when EGADUMP is loaded will
- cause a formfeed to be sent to the printer. The
- switch can be invoked as follows;
-
- EGADUMP /F
-
- The switches /I or /F may be used in tandom and
- may be invoked as follows;
-
- EGADUMP /I /F
-
-
- Technical:
-
- EGADUMP inserts itself into the Interrupt 5 (print screen)
- chain. When the print screen key is depressed,
- EGADUMP will get control (if it is loaded last) and
- determine which video mode is active. If it is
- one of the modes listed above, then EGADUMP will
- handle sending the screen to the printer. If it is not
- one of the above modes, then EGADUMP passes control
- back to the routine that would have been called, had
- EGADUMP not been loaded.
