After a cold reset, print an IO Configuration page to confirm that factoryreset values have been assigned. CAUTION: A factory-installed HP Jetdirect X.509 certificate will be saved over a cold reset to factory default values. However, a Certificate Authority (CA) certificate that has been installed by the user to validate a network authentication server will not be saved. See also The printer behaves strangely on page 231. Control network protocols The printer can simultaneously support multiple network communication protocols. This allows network computers that may be using different protocols to communicate with the same printer. Each protocol may require some configuration before the printer can communicate on the network. For some protocols, required parameters are automatically sensed and user-specified settings are not needed. However, for other protocols, there may be many parameters to configure. Enable or disable network protocols If a network protocol is enabled, the printer may actively transmit on the network even when there are no computers on the network that use the protocol. This may increase network traffic. To eliminate unnecessary traffic, you can disable unused protocols. Disabling unused protocols lets you: ● Reduce network traffic by eliminating broadcast messages from unused protocols ● Provide better control over who prints to the printer by eliminating users from other networks who might route print jobs to this printer ● Display protocol-specific error conditions for enabled protocols only To disable unused protocols through the device's control panel menu, see Front-panel menu items on page 37. For other tools, such as system command access to the embedded Telnet server, see the HP Jetdirect Print Server Administrator's Guide for your print server model. Front-panel menu items Menu item TCP/IP Sub-menu item Host Name Sub-menu item Values and Description An alphanumeric string, up to 32 characters, used to identify the device. This name is listed on the HP Jetdirect configuration page. The default host name is NPIxxxxxx, where xxxxxx is the last six digits of the LAN hardware (MAC) address. ENWW Reset network parameters 37
