Epson 420i - Manual (Page 4)

INTRODUCTION
The Epson 420i is a high speed business printer which is usable with almost all commer-
cial software, including word processing and graphics programs. By changing one switch
on the back of the printer, either the Epson Printer mode or the IBM Graphics Printer
mode is selectable. The two modes differ in character sets and some printer commands.
In contrast with the IBM Graphics Printer, the Epson 420i prints italic characters. Most
programs written for the IBM Graphics Printer do not attempt to print them.
The IBM Graphics Printer mode is selected when extended characters are to be used,
or when software is limited for use with the IBM Graphics Printer.
Refer to the sections tied ‘DIP Switch Setting” (page 26), “Code Table” (pages 30 through
32) and “Differences between the Epson Printer Mode and the IBM Graphic Printer Mode”
(page 36) for details on use of each mode.
