PRINTER CONTROL COMMANDS
The printer has two emulation modes: Standard mode and IBM mode.
In standard mode, the printer emulates the functions of the Epson LQ-860.
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 EDS switch A- 1. When ON, the
printer will be in standard mode, and when OFF, the printer will be in IBM
mode (see Chapter 3). It is not possible to change the emulation mode 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 com-
mands, all commands will be categorized by function. The name of each
command is followed by a table like the one below:
