The printer selection <PARAMTRS> are for the map <MAP_EM> only.  Regular text
should output to any printer.  The printer port is set with <PTRPORT>.

The map is printed using bit-mapped (bit image) graphics.  This is controlled
from the software with what are called "Escape Codes".  These are non-printing
characters which effect the microprocessor in your printer.

I have two printers with which to experiment.  The first is a Seikosha SP-1000A
9-pin printer left over from the haydays of the Apple II.  Since Epson is a
Division of Seiko (or is it the other way?), I presume that the same codes will
work on any Epson 9-pin printer.  I also wrote an alternate 9-pin printer
driver which uses less esoteric commands.  But try the Seikosha routine first.

My new Panasonic KX-P2124 24-pin printer seems to have no native mode.  It can
emulate Epson LQ-860 or IBM Proprinter X24E (with or without Alternate Graphic
Mode).  Again, there is a simplified command set which might work better on
other 24-pin printers.  Try them all.  File SQUARE1.PLT should plot square.

To support your printer, I need to know the escape command codes for the bit
mapped or bit image graphics.  This is NOT the "graphics" mode which prints the
hiASCII characters like ͼ or .  Also I will need the codes to set line
feed to n/60 or n/72 inch, initialize, and set form feed to n inches.  This
information should be in your owner/operator manual.
