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.
