Using MFP menus Serial Use these menu items to change printer settings affecting jobs sent to the MFP through an optional serial port. Menu item PCL SmartSwitch PS SmartSwitch NPA Mode Serial Buffer Serial Protocol Purpose Values and descriptions Configures the MFP so it On* automatically switches to PCL emulation when a print job received Off through the serial port requires it, regardless of the default printer language. On-The MFP examines the data at the serial interface and selects PCL emulation if the data indicates that is the required printer language. Off-The MFP does not examine the incoming data. The MFP 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. Configures the MFP so it On* automatically switches to PostScript emulation when a print job received Off through the serial port requires it, regardless of the default printer language. On-The MFP examines the data at the serial interface and selects PostScript emulation if the data indicates that is the required printer language. Off-The MFP does not examine the incoming data. The MFP 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. Specifies whether the MFP performs the special processing required for bidirectional communication, following the conventions defined in the Network Printing Alliance (NPA) Protocol. Note: Changing this menu item automatically resets the MFP. It is reset to configure memory, and any permanent resources, such as fonts or macros, are lost. On Off Auto* The MFP performs NPA processing. If data is not in NPA format, it is rejected as bad data. The MFP does not perform NPA processing. The MFP examines the data to determine the format and then processes it appropriately. Configures the size of the serial input buffer. Note: Changing the Serial Buffer menu item automatically resets the MFP. Any permanent resources, such as fonts or macros, are lost. Auto* 3KB to maximum size allowed (1KB increments) The MFP automatically calculates the Serial Buffer size (recommended setting). The user specifies the Serial Buffer size. The maximum size depends on the amount of memory in the MFP, the size of the other link buffers, and whether Resource Save is set to On or Off. To maximize the range for the Serial Buffer size, disable or reduce the size of the parallel and USB buffers. Selects the hardware and software DTR* handshaking values for the serial interface.
