Disable protocols
In some cases, you might want to disable all protocols that you do not plan to use to access your printer. For example,
you might prevent users from sending files via ftp or connecting through telnet to manage the printer network
settings. You can disable unused protocols through the Mgmt. Protocols option in the Embedded Web Server, or the
Network Enable Features in Web Jetadmin.
In the HP DesignJet T830 MFP/T730 printer, the network Management Protocols can be configured from the Network
> Advanced Settings menu.
