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 1SQUARE1.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 .
