USB Item 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
Communication
Mode
Select the highest level of USB communication capabilities
when the print server tries to establish a communication
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.
