Dot Matrix ~ Impact Printer
This Epson MX-100 printer is in excellent condition! Use with any Apple II with a parallel printer card in one of the slots (usually slot 1), or any computer with a parallel interface or port. The previous owner attached a few stickers to show dip switch settings and a reminder of how many characters wide it would print. This printer came from an Apple II environment, so should be ready to go!
This is the wide carriage version of one of the first and probably most popular printers ever, the Epson MX-80. Epson MX-100 became available in early 1982. The MX-100 is a 136-column wide carriage model, and can print hi-res graphics without the need to add any special hardware. The MX-100 was released with a 15-inch platen to accomodate larger sheets of paper for printing spreadsheets and other forms of output which couldn’t be printed on 8 1/2″ paper. The MX-100 also included an improvement in the firmware which allowed it to print in higher resolution graphics, skip-over perforations, program the right margins, and print in a total of eight international character sets. Epson dot matrix printers were unique because they featured a “double print” mode where a line was printed normally, then the paper was advanced 1/216 of an inch and the same line printed again. This filled in some gaps between dots on individual letters, and made printouts more pleasing to the eye. Another feature was a mode in which the pins hit the ribbon harder and made it possible to make multiple copies using carbons.
