║║║╠═╝║║║ - print is a utility which allows any Epson
║ J printer to print IBM graphics characters
in a way that is completely transparent to
you (the user) or any program or operation
on the computer (including PrintScreen).
When it is installed, MPM-print becomes
memory-resident, that is, it stays active
in a small portion of your computer's
memory until your computer is turned off
or "rebooted".
After it is installed, MPM-print allows an
Epson printer to print 240 of the 255
graphics characters that IBM PC monitors
can display (which is more IBM characters
than even the IBM Graphics Printer can
print).
MPM-print is an ideal addition to your
"AUTOEXEC.BAT" file; if it is included, it
will be installed in memory whenever you
restart your computer, and will then
always allow IBM's special characters to
print on your printer.
The system will work with Epson FX, MX
(with Graftrax Plus), and RX series
printers, AND with the IBM Graphics
Printer (which is a version of the Epson
MX printer). MPM-print uses less than
3000 bytes of system memory when it is
installed, and will work with PC-DOS
versions 1.1 and above.

INSTALLATION MPM-print is installed simply by typing
▀▀▀▀▀▀▀▀▀▀▀▀ its name at the DOS prompt, i.e.
DOS prompt
└───┬────┘A
│
A>MPMprint <enter>
│ │
┌────┴─────┐ └─ carriage return or
program name enter key
MPM-print will then "attach" itself to
DOS, and will print the following message
to the screen:

After it has been installed, MPM-print
cannot be re-installed (except in unusual
circumstances, see TECHNICAL NOTES below).
If you try to reinstall the system MPM-
print will give you the following message:
A ╔╦╗╔═╗╔╦╗
║║║╠═╝║║║ - print

is already installed

USE After it has been installed, MPM-print is
▀▀▀ completely transparent both to you (the
user) and to programs running on your
computer.
MPM-print "reviews" each character that is
sent to the printer, and takes one of four
actions:
1. If the character is "shared" by
Epson and by the IBM monitors, it will
be printed normally. Only the
"standard" ASCII characters, ranging
from the space (ASCII 32) to the ~
(ASCII 126) are shared.
2. If the character is an Epson
control character, it will be passed
without change to the printer (see
Appendix B for a listing of all Epson
control codes).
3. If the character is an Escape
(ASCII 27), MPM-print will send the
Escape character AND the appropriate
number of following characters to the
printer without change (Epson printers
use "Escape sequences" to control a
wide variety of printing functions.
See Appendix B for a listing of Epson
escape sequences).
4. Finally, if the character is one of
the 145 characters that are neither
"shared" nor printer control
characters, then MPM-print will
"translate" the character and print the
IBM monitor's version of that character
using the Epson printer's graphics
capability.

TESTING Included with MPM-print are two versions
▀▀▀▀▀▀▀ of a testing program, TEST.COM and
TEST.PAS. Written in TURBO Pascal, the
testing programs will "exercise" most of
the print commands available for the Epson
printers.
For each control code and escape sequence
(see Appendix B), the program will set the
printer's mode, then (if appropriate) it
will print the 240 non-control characters,
and finally will restore the printer to
its original mode.
The purpose of the test is to verify that
MPM-print will properly transmit the
control codes/escape sequences to the
printer, and that it will properly print
the full 240 MPM-print character set after
setting the printer's mode.
TEST.COM was compiled using TURBO Pascal
version 3.0, and will only run with DOS
2.0 or higher.
The source code (TEST.PAS) is provided to
allow the user to study the use of the
Epson control codes and escape sequences,
and to convert the testing program to
other languages.
The compiled version of TEST will take 20-
25 minutes to run (it is limited by the
speed of the Epson printers), and will
print about seven pages.

TECHNICAL NOTES SPEED
▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ═════
MPM-print uses the graphics printing
capabilities of the Epson printers to
produce the 145 IBM characters that the
Epson printers normally don't print.
Printing using the graphics mode requires
more information and effort on the part of
the printer, so the 145 non-Epson
characters take longer to print. (This is
why the 'TEST' program takes so long to
print 7 pages of output). "Normal" text
is printed at the normal rate of speed.
If your text makes use of a large number
of the IBM's "special" characters, the
text printing will be significantly slower
than it would have been if you wanted to
look at the funny characters that the
Epson uses in place of the IBM characters.
If, however, your text contains relatively
few "special" characters, then printing
will be virtually as fast as it would be
WITHOUT MPM-print installed.
LINE SPACING
════════════
Because of limitations with certain Epson
printers, the graphics characters printed
by MPM-print are 8 dots high. Therefore,
to get any of the vertical bar characters
(used for drawing boxes, or for the MPM
logo, for example) to print contiguously
(without any vertical white space between
them), the printer must be set to print 8
dots per line. This can be done by
sending the escape sequence ESCAPE 65 8 to
the printer (see the listing of escape
code sequences in Appendix B).
CHARACTER SIZES
═══════════════
The IBM characters that MPM-print produces
are printed in the normal (pica) mode.
Although MPM-print will allow a program to
set the printer to any mode (expanded,
compressed, etc.), the IBM characters will
still be printed in the pica mode.

TECHNICAL NOTES EPSON CONTROL CODES
▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ═══════════════════
Epson printers use certain one-byte codes
(ranging from ASCII 7 to 27) to control
some of the printers' features (see
Appendix B). Each feature can be
activated by sending EITHER the code OR
the code+128 to the printer (for example,
both ASCII 7 and ASCII 135 would "beep"
the printer's speaker). We have chosen to
print IBM characters for all ASCII codes
above 127, since printer control codes are
already provided by ASCII characters 7-27.
We have also chosen to print the IBM
character (ASCII 127) instead of the
"delete" code for the Epson printers. The
"delete" code deletes the last character
in the Epson printer's line buffer; since
it is rarely used, we chose to print the
IBM character instead.
All other control codes and escape
sequences (see Appendix B) are passed
directly to the printer.
REMOVING (de-installing?) MPM-print
═══════════════════════════════════
Reboot your computer (using the Ctrl-Alt-
Del keys simultaneously), and DON'T run
MPM-print after rebooting.
REINSTALLING MPM-print (or trying to)
═════════════════════════════════════
MPM-print works by taking control of
IBM's ROM BIOS interrupt 17h (Printer
I/O). When you try to re-run MPM-print,
it checks the ROM BIOS interrupt to see
if it has already been installed. If it
has, MPM-print will notify you of that
fact.
A problem can occur, however, if you
install some other piece of memory-
resident software (such as a print
spooler; please read the following
section) that also takes control of
interrupt 17h AFTER MPM-print has been
installed. If this is the case, and IF
you try to re-run MPM-print, it will NOT
find a copy of itself when it checks, and
it WILL proceed to install itself again.

TECHNICAL NOTES PRINT SPOOLERS
▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ══════════════
Print spoolers are memory-resident
programs that "reserve" a portion of
memory to buffer information that is sent
to the printer.
Ideally, MPM-print should be installed
BEFORE a print spooler. This would allow
your print spooler to hold characters as
single bytes, and would let MPM-print
handle sending the special characters to
the printer in graphics mode.
HOWEVER, some print spoolers (notably
AST's SUPERSPL) will ignore the existence
of MPM-print IF they are installed after
MPM-print. If you are using one of those
spoolers, then please install MPM-print
AFTER installing your print spooler.
COMPATIBILITY
═════════════
We have not been able to test MPM-print
with every available piece of software.
We HAVE, however, tested it with:
IBM PC-DOS versions 1.1,2.1,3.0,3.1
PrintGraph/Lotus 1-2-3
Graphics screen dumps (as long as the
DOS utility GRAPHICS.COM is also
installed)
Sidekick (from Borland International)
PC-WINDOW (a user supported, memory-
resident system utility from:
Cannon/Mill Software, PO Box 10047,
Columbia, MO 65205)
The following user supported "quality
printing" systems:
LQ-PRINT (from:
Centar Technology, PO Box 60577,
Sunnyvale, CA 94088)
BRADFORD (from:
Aaron Contorer, 1521 Central Ave.,
Deerfield, IL 60015)
PC-FONT (v 2.04, from:
SJL, 4473 Marlborough, #5
San Diego, CA 92116)
If you have compatibility problems with
other memory-resident programs, the first
thing to try is changing the order in
which the programs are loaded into memory.
If you discover compatibility problems
that you are unable to solve, please let
us know about them.
