PJL
3-2
Notes:
•
Parameters enclosed in square brackets ([ ]) are optional and not required
for command execution.
•
The PJL interpreter requires uppercase for the
@PJL
prefix for all PJL com-
mands
except
the Universal Exit Language (UEL) command. The rest of the
PJL command is not case sensitive. The UEL command is case sensitive.
•
All PJL commands except UEL must be terminated with a line feed char-
acter (<LF>).
Kernel Commands
UNIVERSAL EXIT LANGUAGE Command
The Universal Exit Language (UEL) command terminates the current printer language
and allows dynamic switching into PJL.
Syntax:
<ESC>%-12345X
Notes:
•
If the printer receives this command while in PCL emulation, it performs a
Printer Language Reset (
ESC
E) before exiting PCL emulation.
•
If the printer receives this command while in PostScript emulation, it performs
an End-of-Job (EOJ) command before exiting PostScript emulation (Ctrl-D).
The PJL commands must immediately follow the UEL command (that is, the
X
in the
UEL syntax must be immediately followed by the
@PJL
of the next PJL command).
