Some possible problems

Garbled output:
If a string of characters (or binary data) is mistaken as a trigger and an incorrect PDL is applied,
the output will be garbled.
Incorrect printer settings:
Printer settings, for example the paper size, is incorrectly applied. This can happen when the
printer settings at the beginning of the job are initialized before a PDL switch occurred and no
settings were configured for the rest of the job.

Printer Bit Switch description

Bit Switch 2-3
This controls Auto PDL Detection by the PCL interpreter and PS interpreter.
BitSW 2-3=0 (default):
If PDL switching is applied to the job, all of the printer system, PCL interpreter and PS
interpreter will search for switching criteria (triggers).
BitSW 2-3=1:
Only the printer system will search for switching criteria (triggers). PCL/PS interpreters will not.
Bit Switch 5-3
This affects the PDL switching criteria (triggers) used by the printer system.
BitSW 5-3=0 (default):
"%%" is not used as a printer system PS trigger. "%%" will not call the PS interpreter.
