The printer has two emulation modes: Standard mode and IBM mode.
In standardmode, 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 asuperset of these emulations.
Theemulation is changedby means of DIP switch 1.When this switchisset ON,the printer
willbe in standard mode, and when this switch is set OFF,the printer will be in IBM mode
(see Chapter 5).
It isnot possibletochangethe emulation by means of software control.
This chapter describes the printer’s control commands. Some commands are common to
boththe standard and IBM modes. In the descriptions ofthecommands, all commandswill
givenby functions. The name of each command is followed by atable like the one below:
<“27 120 49
