Robust Xon - Lexmark W812 User Reference Manual

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