The printer has two emulation modes: Standard mode and IBM mode.
In standard mode, the printer emulates the functions of the Epson LQ-850. In IBM mode,
the printer emulates the IBM Proprinter X24E.
Additional command codes are included as a superset of these emulations.
The emulation is changed by means of DIP switch 1.When thisswitch is set ON, the printer
will be in standard mode, and when this switch is set OFF, the printer will be in IBM mode
(see Chapter 5).
It is not
possibletochange the emulation by means of software control.
This chapter describes the printer’s control commands. Some commands are common to
both the standard and IBM modes. In the descriptions of the commands, allcommands will
given by functions. The name of each command is followed by a table like the one below:
