4.2 PRINTING FEATURES

4.2.1 BEHAVIOR OF USB PRINTER DETECTION

An MFP connected via USB sends its product name and unique serial number. With the data,
the machine determines whether requires a printer driver for the USB device to be installed.
SP5-844-005 allows you to change how to determine the MFP requires a printer driver
installation:
•
OFF
If SP5-844-005 is set to OFF, the unique serial number of the device is sent to the computer.
As a result, if the device is swapped out for a device of the same product, pop-up
messages will appear, because the serial numbers between the two are different.
•
Level 1
If SP5-844-005 is set to Level 1, a common serial number for the product such as "MP
305+" series is sent to the computer. As a result, if the device is swapped out for a device
of the same product, pop-up messages will not appear because the devices are recognized
as having the same serial number.
•
Level 2
If SP5-844-005 is set to Level 2, a common serial number for all GW/GW+ models is sent
to the computer. As a result, if a GW/GW+ device is swapped out for a different GW/GW+
device, pop-up messages will not appear because the devices are both recognized as
being based on GW/GW+.

4.2.2 AUTO PDL DETECTION FUNCTION

Overview

The Auto PDL Detection function gives the MFP 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.
