To
Set the printer to automatically switch to PCL emulation when a print job received
through a serial port requires it, regardless of the default printer language.
Notes:
•
On is the factory default setting.
•
When set to Off, the printer does not examine incoming data. The printer uses
PostScript emulation if PS SmartSwitch is set to On. It uses the default printer
language specified in the Setup menu if PS SmartSwitch is set to Off.
Set the printer to automatically switch to PS emulation when a print job received
through a serial port requires it, regardless of the default printer language.
Notes:
•
On is the factory default setting.
• When set to Off, the printer does not examine incoming data. The printer uses
PCL emulation if PCL SmartSwitch is set to On. It uses the default printer
language specified in the Setup menu if PCL SmartSwitch is set to Off.
Set the printer to perform the special processing required for bidirectional
communication following the conventions defined by the NPA protocol.
Notes:
• Auto is the factory default setting. Auto sets the printer to examine data,
determine the format, and then processes it appropriately.
• When set to On, the printer performs NPA processing. If the data is not in NPA
format, it is rejected as bad data.
•
When set to Off, the printer does not perform NPA processing.
•
Changing this setting from the printer control panel and then exiting the
menus causes the printer to restart. The menu selection is then updated.
Set the size of the serial input buffer.
Notes:
•
Auto is the factory default setting.
•
Disabled turns off job buffering. Any jobs already buffered on the disk are
printed before normal processing is resumed.
•
The serial buffer size setting can be changed in 1‑KB increments.
•
The maximum size allowed depends on the amount of memory in the printer,
the size of the other link buffers, and whether Resource Save is set to On or
Off.
•
To increase the maximum size range for the Serial Buffer, disable or reduce
the size of the parallel, serial, and network buffers.
•
Changing this setting from the printer control panel and then exiting the
menus causes the printer to restart. The menu selection is then updated.
