- EPSON.COM KERMIT DISTRIBUTION JANUARY 1990
-
- The EPSON.COM program is a utility that lets you print IBM PC EGA graphics
- screens on Epson FX and RX printers, just as the IBM-supplied GRAPHICS.COM
- program lets you print CGA graphics screens on IBM printers. Here is the
- author's note:
-
- This routine is public domain for those of you who bought an EGA and
- enhanced monitor and determined that you could no longer do a
- Shift_Print_Screen in mode 10h (16). If you have an IBM compatible and
- an Epson FX series printer then this routine will replace the
- GRAPHICS.COM routine. I also have routines for Radio Shack DMP printers
- with 8 pins (but only 7 usable for graphics) and for HP LaserJet
- printers when used with an EGA. Enjoy...

- INSTALLATION OF EPSON.COM
-
- First make sure you have not run IBM's GRAPHICS.COM. If you have, then
- remove the invocation of GRAPHICS.COM from your AUTOEXEC.BAT file and
- reboot your PC (Ctrl-Alt-Del).
-
- Run EPSON.COM only once after you start your PC. Once you start the program,
- it installs itself in memory as a DOS-level printer driver for the remainder
- of your DOS session, occupying about 2K of memory. There is no way to remove
- it. To avoid memory fragmentation, it is best to run EPSON.COM from your
- AUTOEXEC.BAT file. For example, if you have placed EPSON.COM in the top-level
- (root) directory of your C disk, you would add this line to AUTOEXEC.BAT:
-
- C:\EPSON.COM
-
- This will install EPSON.COM automatically every time you boot your PC.
-
- USING EPSON.COM
-
- To print your current screen, hold down the Shift key and press Print Screen
- or PrtSc.
-
- For TEXT SCREENS, printing will be normal, across the page, and you
- may also turn printing on and off using Ctrl-Print-Screen or Ctrl-PrtSc.
-
- GRAPHICS SCREEN images will come out sideways on the printer, left side on
- top. Make sure your screen background color is set to black (for example,
- using the MS-DOS Kermit command SET TERMINAL COLOR 0), or else the printout
- will be solid black.
-
- PROBLEMS
-
- This program apparently does not recover from Offline indications (that
- happen, for example, when the printer runs out of paper), so if you have a
- long graphics screen, make sure you have enough paper.
-
- BUILDING FROM SOURCE
-
- The EPSON.COM program is furnished on the MS-DOS Kermit 3.0 Distribution
- Diskette. Also included is the assembly-language source file, EPSON.ASM.
- If you want to rebuild the program from the source, do this:
-
- MASM EPSON;
- LINK EPSON;
- EXE2BIN EPSON.EXE EPSON.COM
- DIR EPSON
-
- If you don't see EPSON.COM in the directory listing, but you do see EPSON.BIN,
- do this:
-
- REN EPSON.BIN EPSON.COM
-
- Now copy the EPSON.COM file to the disk and directory you want to run it from.
-
- Programmers are encouraged to adapt this program to work with other kinds of
- display adapters (such as the VGA, Hercules, etc), and other kinds of printers
- (like Postscript), and submit their work to Columbia University for further
- distribution.
