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 printer.

Off

Printer performs NPA processing.

If data is not in NPA format, it is

rejected as bad data.

Printer does not perform NPA

processing.

Auto*

Printer examines the data to

determine the format and then

processes it appropriately.

PCL

SmartSwitch

To configure the printer so it

automatically switches to

PCL emulation when a print job

received through the USB port

requires it, regardless of the

default printer language.

On*

Printer examines the data on the

USB interface and selects

PCL emulation if the data indicates

that is the required printer

language.

Off

Printer does not examine the

incoming data. The printer 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.

SmartSwitch

To configure the printer so it

automatically switches to

PostScript emulation when a print

job received through the USB port

requires it, regardless of the

default printer language.

On*

Printer examines data on the USB

interface and selects

PostScript emulation if the data

indicates that is the required

printer language.

Off

Printer does not examine the

incoming data. The printer 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.

USB Buffer

To configure the size of the USB

input buffer.

Note:

Changing the USB Buffer

menu item automatically resets the

printer.

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

size allowed

User specifies the USB Buffer size.

The maximum size depends on the

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.
