5.Software Configuration
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.
BitSW 5-3=1:
"%%" is used as a printer system PS trigger.
The reason that "%%" is not included as a trigger by default, is that a string of text in the body of the job such as
the below, could result in a false positive. This would trigger a switch and result garbled output.
%%%%%%%%%%%%%%%%%%%%%%%%%%%
However some customers prefer that "%%" be included as a switching criteria. BitSW5-3=1 should be used in
such a case.
• A side effect of BitSW5-3=1 is that "userdict" will no longer be used as a PS trigger.
Bit Switch 9-0
These determine whether Auto PDL Detection for print jobs transmitted via USB/parallel will wait 10 seconds to
make sure the first 2KB of the job has been sent.
The Printer system portion of the Auto PDL Detection function is only performed on the first 2KB of a job and
can wait up to 10 seconds for that first 2KB to arrive. As the printer is unable to detect the end of jobs submitted
over a USB/Parallel connection, it might be preferable to not wait 10 seconds if jobs of less than 2KB are going to
be printed. Enabling/disabling this waiting time is the purpose of BitSw 9-0.
BitSw 9-0=0 (default):
