To
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.
Temporarily store print jobs on the printer hard disk before printing.
Notes:
•
Off is the factory default setting. The printer does not buffer print jobs on
the printer hard disk.
•
On buffers print jobs on the printer hard disk.
•
Auto buffers print jobs only if the printer is busy processing data from
another input port.
•
Changing this setting from the printer control panel and then exiting the
menus causes the printer to restart. The menu selection is then updated.
Select the hardware and software handshaking settings for the serial port.
Notes:
•
DTR is the factory default setting.
•
DTR/DSR is a hardware handshaking setting.
•
XON/XOFF is a software handshaking setting.
•
XON/XOFF/DTR and XON/XOFF/DTR/DSR are combined hardware and
software handshaking settings.
