Table 4-14 USB Settings Tab 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. Preferred USB 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. ● AUTO (default): The print server will 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: This level 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): 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. Status Page Language Select the Page Description Language (PDL) for the 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.
