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.

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 39 . 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.
