Some possible problems
Garbled output:
If a string of characters (or binary data) is mistaken as a trigger and an incorrect PDL is applied,

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.
