Auto PDL Detection Function
Overview
The Auto PDL Detection function gives the MFP/LP the ability to determine the PDL of a job or of specific parts
of a job. This can be especially useful in cases where the PDL is not specified or if the job contains multiple
PDLs. This is only possible if the job was not created using a driver.
Conditions for detection of the PDL
The MFP will only attempt to detect a job's PDL if all of the following conditions are met.
• No @PJL ENTER LANGUAGE command is contained in the job
• No submission protocol options (lpr, ftp, rcp, or rsh options) have been used to specify the PDL
User Tools > Printer > System > Printer Language = Auto
•
• The printer is unable to detect PCL6 or RPCS. However these are almost always created using a driver
and therefore contain the PJL command specifying the PDL.
PDL detection by the printer system, PCL interpreter and PS interpreter
There are 3 components in the printer which can perform Auto PDL Detection:
Printer system:
1.
Uses a set of triggers unique to PCL5, PS or PDF. Up to 2KB from the start of the job can be searched for
triggers.
PCL interpreter:
2.
It can detect PS triggers in PCL data. If a PS trigger is detected, the PCL interpreter will abort processing and
return the unprocessed part of the job back to the printer system. Up to 256 bytes from the start of each page
can be searched for triggers.
3. PS interpreter:
It can detect PCL5 triggers in PS data. If a PCL trigger is detected, the PS interpreter will abort processing
and return the unprocessed part of the job back to the printer system. The entire page (regardless of the
number of bytes) is searched for triggers.
• 2. and 3. can be disabled using Printer Bit Switch 2-3=1.
• If the "Printer Language" is configured to anything other than Auto, all detection will be disabled.
• An interpreter submits a job page by page to the rasterizer. Therefore, when an interpreter detects a
trigger mid-job, the previous pages will have already been submitted and will be output using the
previously detected PDL.
