If PCL SmartSwitch is set to On, the printer examines the data
on the LocalTalk interface connection and selects PCL
emulation if the data indicates that is the printer language.
If both PCL SmartSwitch and PS SmartSwitch are set to Off,
the printer uses the language specified in the Printer Language
menu as the default. If only one SmartSwitch setting is set to
On, the printer uses that language as the default.

If PS SmartSwitch is set to On, the printer examines the data on
the specified LocalTalk interface connection and selects
PostScript emulation if the data indicates that is the printer
language.
If both PCL SmartSwitch and PS SmartSwitch are set to Off,
the printer uses the language specified in the Printer Language
menu as the default. If only one SmartSwitch setting is set to
On, the printer uses that language as the default.

NPA is a mode of bidirectional communication that follows the
conventions defined in Network Printing Alliance Protocol, a
Printer/Host Control Specification developed by the NPA. NPA
mode requires special processing of the print data.
If NPA Mode is set to Off, the printer does not perform any NPA
processing. If NPA Mode is set to Auto, the printer examines
the data to determine the format and then processes it in either
format.
The NPA Mode setting in the LocalTalk Menu applies only to the
LocalTalk interface connection.
Note: Changing the NPA Mode setting automatically resets the
printer.
