The printer has two emulation modes: Standard mode and IBM mode.
In standard mode, the printer emulates the functions of the Epson LQ-1050.
In IBM mode, the printer emulates the IBM Proprinter XL24. Additional
command codes are included as a superset of these emulations.
The emulation is changed by means of DIP switch l-6. When ON, the printer
will be in standard mode, and when OFF, the printer will be in IBM
emulation mode (see Chapter 3). It is not possible to change the emulation
mode by means of software control or the front control panel.
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 given by function. The name of each command
is followed by a table like the one below:
Mode ASCII Decimal Hexadecimal
Both <ESC> “x1’ “1” 27 120 49 18 78 31
<ESC> ‘Ix” <l> 27 120 1 1B 78 01
Mode: Indicates the mode in which the command is recog-
nized.
Std. Standard mode (DIP switch l-6 on)
IBM IBM mode (DIP switch l-6 off)
Both Both standard and IBM modes
ASCII: Indicates the ASCII coding of the command.
Control characters are enclosed in pointed brack-
ets: For example, co> means character code 0.
Decimal: Gives the command in decimal character codes.
Hexadecimal: Gives the command in hexadecimal character
codes.
Parameters for which values must be supplied are indicated by italic letters
such as n.
