A-2.1 Basic Rules for PJL Programming

Printer Job Language (PJL) command sequences are used to define all specific
parameters for one print job. PJL commands provide the following major
functions:
Printer language switching between jobs
$
Job separation
$
Printer configuration
$
Status readback from the printer to the host
$
At the beginning of every print job the UEL command ( ESC % - 1 2 3 4 5 X ) is
used to switch from the print emulation (PCL, Postscript, HEXDUMP...) to the
PJL command level.
A-2.1.1 PJL Syntax Rules
Use only uppercase characters
$
All parts of a PJL command line must be separarted by a <SP> (Space)
$
Every PJL command line must start with the prefix @PJL.
$
Every PJL command line must end with <LF> (Line Feed)
$
Sample of typical PJL command line:
@PJL <SP>DEFAULT<SP> LPARM : PCL <SP> PTSIZE = 12<LF>
PREFIX <SP> COMMAND <SP> Com. Modifier : Value <SP> Variable = Value<LF>
The fist PJL command after the UEL must start with @PJL....! (no <SP>)
