Printing Features
D0CA/D0C9/D0C8/D0CB 4-6
SM Appendices
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):
The printer system will not wait 10 seconds for the first 2KB of data to arrive.
BitSw 9-0=1:
The printer system will wait up to 10 seconds for the first 2KB of data to arrive.
4.2.3 PRINT IMAGES ROTATION
Printer Bit Switch description
Bit Switch 5-6
This changes the way an MFP/LP rotates PCL, PS, PDF, or RPCS print images.
BitSW 5-6=0 (default):
A uniform binding edge (short or long edge) will be applied to every page of every job. Pages
will always be rotated as if they were to be bound on that edge.
BitSW 5-6=1:
A uniform binding edge (short or long edge) will only be applied if the job is stapled, punched, or
Z-folded. Otherwise, the bound edge might differ from page to page.
