Emulations
General
When a printer understands the control set written for another printer type, it is said to
emulate the other printer. Your printer emulates, i.e. “understands” the DEC PPL2,
Epson LQ-2550 and IBM Proprinter emulations in its standard version.
Escape sequences
Escape sequences or control codes tell the printer that the following transmitted
code is a printer command and not a printable character
They allow the selection of printer functions or the changing of printer parameters
from the computer. By transmitting an escape sequence, you are able to change
the previously set configuration of the printer (e.g. character set).
This chapter contains an introduction into the sequences and control codes which
are used by your printer.
The settings made by escape sequences have priority over the settings made in
menu mode; therefore they override these.

What are escape sequences?
An escape sequence consists of an ESCape control character (ESC = decimal 27 or
hexadecimal 1B) followed by one or more characters, which represent commands to
the printer. Please note that this escape character has nothing to do with the ESC key
on your computer keyboard.
For example, the control character ESC followed by the character “4” tells your
printer to print the subsequent text in italics.
How are escape sequences used?
Escape sequences are transmitted to the printer by your computer software via the printer driver.
Experienced users and programmers can also control the printer directly via control sequences,
however before you start working with escape sequences and control codes, we recommend that you
study the computer software manual.
To enter control codes the Ctrl key and an ASCII character must be pressed simultaneously. For
instance, by pressing Ctrl and J a line feed is accomplished (it is required to output the character string
on the printer). More information concerning this topic is contained in your computer software manual
and the corresponding Programmer’s Application Manuals (see section Programming manuals).
The selected emulation must correspond to the printer driver of your application
program. Settings caused by ESC sequences remain valid, until they are switched off
by another control code. All settings are reset to the original menu, whenthe printer is
switched off.
