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
STOP
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, when the printer is switched off.

MTPL

As the emulations do not cover the entire scope of your printer, a new printer
language, which is adapted to this printer model, has been created. Using MTPL
you are able to optimize operation and handling.
MTPL can be used in connection with other emulations or can be used alone.

Example in BASIC

open "LPT1:" as #1
width #1,255
Text1$ = "10 characters/inch"
Text2$ = "15 characters/inch"
ESC$ = chr$(27)
print
#1,ESC$;"[4w";Text1$;ESC$;"[6w";Text2$;ESC$;"[4w";Text1$
end

Example in Pascal

program cpi_example;
uses printer;
const ESC = #27;
Text1 = "10 characters/inch";
Text2 = "15 characters/inch";
begin
writeln(lst,Esc,"[4w",Text1,ESC,"[6w",Text2,Esc,"[4w",Text1);
end.

Printout

After the program has been completed the following text will be printed out:
10 characters/inch 10 characters/inch
15 characters/inch
