Table 4-15USB Settings tab

Item	Description
USB Speed	(Read-only parameter, for USB 2.0 print servers only.) The auto-negotiated 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-Speed480 Mbits/sec for USB v2.0 devices only.
	● Disconnected USB port is not connected.
Preferred USB	Highest level of USB communication capabilities when the print server tries to establish a
Communication Mode	communication level with the printer. If you change the current setting, unplug and then
	reconnect the USB cable, or turn the print server off and then on, to activate it.
	● AUTO (default) Automatically attempt to set the highest level available, starting with
	multiple interface (composite) USB devices, followed by IEEE 1284.4 and Multiple
	Logical Changes (MLC). If not successful, subsequent levels are attempted.
	● IEEE 1284.4 Allows multiple channels of simultaneous print, scan, and status
	communication, but without composite USB support. If not successful, subsequent
	levels are attempted.
	● Multiple Logical Channels (MLC) An HP-proprietary protocol that allows
	multiple channels of simultaneous print, scan, and status communication.
	● Bidirectional Basic two-way printer communications. Print data is sent to the
	printing device, and status information is returned.
	● Unidirectional One-way printer communication from the print server to the printing
	device. (This is the lowest communication level.)
	The communication level set by the print server is reported on the HP Jetdirect
	configuration page.
Status Page Language	Page description language (PDL) for the HP Jetdirect configuration page data sent to the
	printer. Available options include PCL, ASCII, PostScript and HPGL2.
	When set to AUTO (default), the print server automatically attempts to detect and select a
	language supported by the device. Typically, HP-PCL is selected if available.
