Description
Sets the printer to automatically switch to PS emulation when a print job
received through a USB 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 the PCL SmartSwitch is set to On. It uses the
default printer language specified in the Setup menu if the PCL
SmartSwitch is set to Off.
Sets 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 process it appropriately.
•
Changing this setting from the printer control panel and then exiting the
menus causes the printer to restart. The menu selection is then updated.
Sets the size of the USB input buffer
Notes:
•
Auto is the factory default setting.
•
Disabled turns off job buffering. Any jobs already buffered on the printer
hard disk are printed before normal processing resumes.
•
The USB buffer size value 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 USB 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 stores print jobs on the printer hard disk before printing
Notes:
•
Off is the factory default setting.
•
On buffers 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.
Sets the printer to process Macintosh binary PostScript print jobs
Notes:
•
Auto is the factory default setting.
•
On processes raw binary PostScript print jobs.
•
Off filters print jobs using the standard protocol.
