PCL SmartSwitch
Purpose:
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.
Values:
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. |
