The printer selection are for the map only. Regular text should output to any printer. The printer port is set with . 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 ÉÍÎͼ or àýê. 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. Access to the entire text files is thru .
