Description

 

 

USB Speed

(Read-only parameter, for USB 2.0 print servers only).

 

Specifies the autonegotiated communication speed over

 

the USB connection between the print server and the

 

device.

 

Full Speed: 12 Mbits/sec as specified in the USB v2.0

 

specifications, compatible with USB v1.1 specifications.

 

Hi-Speed: 480 Mbits/sec for USB v2.0 devices only.

 

Disconnected: The USB port is not connected.

 

 

Desired

Select the highest level of USB communication capabilities

Communication

when the print server tries to establish a communication

Mode

level with the printer. If you change the current setting,

 

unplug and then reconnect the USB cable, or power the

 

print server off/on, to activate it.

 

Automatic (default): The print server will attempt to set

 

the highest level available, starting with IEEE 1284.4. If

 

not successful, subsequent levels are attempted.

 

IEEE 1284.4: This level is the highest communication

 

level, and allows multiple channels of simultaneous

 

print, scan, and status communication.

 

MLC: (Multiple Logical Channels) The next level is MLC,

 

an HP-proprietary protocol that allows multiple

 

channels of simultaneous print, scan, and status

 

communication.

 

Bidirectional: This level provides basic two-way printer

 

communications. Print data is sent to the printing

 

device, and status information is returned from the

 

printing device.

 

Unidirectional: This is the lowest communication level

 

and provides one-way printer communication from the

 

print server to the printing device.

 

The communication level set by the print server is reported

 

on the Jetdirect configuration page.
