Variables
Variables are actually utilized within the M204’s models and are useful for defining
lengthy header or trailer strings. This might be necessary for certain printer switch
strings, for example. Each variable consists of a combination of escape codes and text
for this printer control.
Variables are used to make efficient use of the limited space in these header and trailer
strings. Only nine elements can be included in these strings. Each element can be one
of the following:
letter
a
code 0x40
variable $FF
Therefore, you could make up a series of variables and specify each of these (up to
nine) in the header or trailer string. Each variable could then contain up to 14 elements
of its own.
Please see Variable Definitions on page 163 for a description of all pre-defined vari-
ables. You can also create your own variables to add to this list.

set model on page 97, and USING NPWIN on page 113.
pcl-ps For printers that cannot autosense the print job format and
switch modes by themselves. Precedes each job with a string
to switch from PostScript to PCL, or vice versa, depending
on job content. These strings must be specified in the setup
command.
a2ps Convert ASCII jobs to PostScript or pass PostScript jobs
directly to PostScript printers.
