NPA Mode Purpose: To specify whether the printer performs the special processing required for bidirectional communication, following the conventions defined in the Network Printing Alliance (NPA) Protocol. Values: On Off Auto* Printer performs NPA processing. If data is not in NPA format, it is rejected as bad data. Printer does not perform NPA processing. Printer examines the data to determine the format and then processes it appropriately. Note: Changing this menu item automatically resets the printer. PCL SmartSwitch Purpose: To configure the printer so it automatically switches to PCL emulation when a print job received through the USB port requires it, regardless of the default printer language. Values: On* Off Printer examines the data on the USB interface and selects PCL emulation if the data indicates that is the required printer language. 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.
