PCL
SmartSwitch
To configure the printer so it
automatically switches to PCL
emulation when a print job
received through the serial port
requires it, regardless of the
default printer language.
On* Printer examines data on the serial
interface and selects PCL
emulation if the data indicates that
is the required printer language.
Off Printer does not examine the
incoming data. The printer uses
PostScript emulation to process
the job if PS SmartSwitch is On, or
uses the default printer language
specified in the Setup Menu if PS
SmartSwitch is Off.
