If you are using a serial interface, turn to Appendix C, which gives
full information on serial interfaces.
The operating mode
The EX has two operating modes, ESC/P
™
and IBM printer emulation
mode. ESC/P stands for Epson Standard Code for Printers, a powerful
set of commands developed by Epson and supported by almost all
application software for personal computers. This is the mode that you
should find the most useful and valuable for your printing. The rest of
this manual refers to the ESC/P mode simply as the Epson mode.
The IBM printer emulation mode is for software that is designed only
for IBM printers. It is not necessary to use this mode for your EX to be
compatible with IBM computers. As you can see from the list of Epson
and IBM printer emulation mode commands in Appendix A, the Epson
mode has more commands and many more capabilities.
There are only two cases in which you may want to use the IBM
printer emulation mode:
1. Your software lists only IBM printers in its printer selection menu.
2. You need to use the following characters and your application
software will not print them in the Epson mode:
If you select IBM printer emulation mode with the DIP switch and
choose an IBM printer in your software’s printer selection menu, your
EX will behave as an IBM printer does. You can use most software that
supports IBM printers, but you will notice that the commands do not
allow you access to all the features of your Epson printer.
DIP switch 1-4 controls the choice of operating modes. Turning the
switch OFF selects Epson mode, and turning it ON selects IBM printer
emulation mode.
