If you ever need to reconfigure an HP Jetdirect, this can be done via telnet. We have a model 170x; however, this procedure will work with many Jetdirect boxes. First off, you need to figure out the current IP address. Do this by pushing the system test button on the Jetdirect box. The current IP address and subnet mask will be listed. Once you have the IP address, bind another address on the same network as the Jetdirect box, and telnet to it:
srv-5:~ usr4$ telnet 10.50.100.8
Trying 10.50.100.8...
Connected to 10.50.100.8.
Escape character is '^]'.

All good. Note that the password can be changed, but there currently is no password. This may be OK for an internal network, but to be safe, consider changing this so that a password is required.
