USB 1.1 and USB 1.1 does not include Hi-Speed. USB 2.0 added Hi-Speed and is fully backward compatible with USB 1.1 in Full-Speed. As a result, some of the newer USB printers cannot be supported. Its eventual replacement is currently available as the en1700, an upgradeable solution that supports Hi-Speed USB and also supports IPv6. The ew2400 and the en3700 which are USB 2.0 Hi-Speed will remain on the CPL for a while as they are respectively HP’s wireless value line external print server and HP’s full featured external print server.

Scanning on AIO and MFP’s

The HP Jetdirect External print servers do not support scanning on Laserjet MFP’s. They are currently a print only solution. The 175x, ew2400, and en3700 supported scanning through the embedded web server for the Laserjet AIO’s and Officejet Pro’s. Many devices have their own networking scanning software and no longer rely on HP JetDirects web scan capability and in many cases no longer support it. As a result, the web scanning capability has been removed from the en1700.

Supported Printer lists

Due to various product limitations, not all USB external print servers support the same set of printers. In this section, I will break down the supported printers for each HP USB Jetdirect print server. As always, be sure your firmware on both the printer and print server is at the latest available version.
