Off MFP examines the data on the USB interface and selects PCL emulation if the data indicates that is the required printer emulation. MFP does not examine the incoming data. The MFP uses PostScript emulation to process the job if PS SmartSwitch is On, or uses the default printer emulation specified in the Setup Menu if PS SmartSwitch is Off.

Using the MFP control panel and menus

Menu item
Purpose
Values and descriptions
PCL SmartSwitch
To configure the MFP so it
automatically switches to
PCL emulation when a print
job received through the USB
port requires it, regardless of
the default printer emulation.
On*
MFP examines the data on the
USB interface and selects
PCL emulation if the data
indicates that is the required
printer emulation.
Off
MFP does not examine the
incoming data. The MFP uses
PostScript emulation to process
the job if PS SmartSwitch is On,
or uses the default printer
emulation specified in the Setup
Menu if PS SmartSwitch is Off.
PS SmartSwitch
To configure the MFP so it
automatically switches to
PostScript emulation when a
print job received through the
USB port requires it,
regardless of the default
printer emulation.
On*
MFP examines data on the USB
interface and selects
PostScript emulation if the data
indicates that is the required
printer emulation.
Off
MFP does not examine the
incoming data. The MFP uses
PCL emulation to process the
job if PCL SmartSwitch is On, or
uses the default printer
emulation specified in the Setup
Menu if PCL SmartSwitch is Off.
NPA Mode
To specify whether the MFP
performs the special
processing required for
bidirectional communication,
following the conventions
defined in the Network
Printing Alliance (NPA)
Protocol.
On
MFP performs NPA processing.
If data is not in NPA format, it is
rejected as bad data.
Off
MFP does not perform NPA
processing.
Auto*
MFP examines the data to
determine the format and then
processes it appropriately.
