Introduction
The NX-2450 Rainbow/Colour has two emulation
modes: Standard/Epson mode and IBM mode.
In the Standard/Epson mode, the printer emulates the
Epson LQ-860/850, and can also recognize the graphics
commands of NEC 24-wire printers. In IBM mode, the
printer emulates the IBM Propnnter X24E. Some addi-
tional command codes, which are a superset of these
emulations, are also supported.
The emulation can be changed by changing Electronic
DIP Switch (EDS) setting Al. When Al is ON, the printer
is in Standard/Epson mode; when it is OFF, the printer
is in IBM mode (see SeZectingwhich emulation to use on
page 46 of Chapter 4).
In addition, when EDS switch A2 is ON, the printer can
automatically sense which emulation is required and
will change emulation as necessary.
This chapter describes the printer’s control commands.
Some commands are comm-onto both Standard and
IBM modes. All commands will grouped by function. The
name of each command is followed by a table like the
one below:
