Printing Features
Behavior of USB Printer Detection
An MFP/LP 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/LP 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+.
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.
