Using the printer menus
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 | Printer performs NPA processing. If data is not in NPA format, it is rejected as |
| bad data. |
Off | Printer does not perform NPA processing. |
Auto* | Printer examines the data to determine the format and then processes it |
| appropriately. |
Note: Changing this menu item automatically resets the printer.
USB Buffer
Purpose:
To configure the size of the USB input buffer.
Values:
Disabled | Job buffering is disabled. Any jobs already buffered on the disk are |
| printed before normal processing of incoming jobs resumes. |
Auto* | Printer automatically calculates the USB Buffer size (recommended |
| setting). |
3K to maximum | User specifies the USB Buffer size. The maximum size depends on the |
size allowed | amount of memory in your printer, the size of the other link buffers, and |
| whether Resource Save is set to On or Off. To maximize the range for |
| the USB Buffer size, disable or reduce the size of the parallel, serial, |
| and network buffers. |
Note: Changing the USB Buffer menu item automatically resets the printer.
