CAUTION
through HTTPS is enabled before creating the initial SNMP v3 account. This will help to
prevent access or interception of account information over a connection that is not secure.
SNMP v1 and v2c agents can coexist with the SNMP v3 agent. However, to fully secure
SNMP access, you should disable SNMP v1 and v2c.

Description
Enable or disable network protocols supported by the print server: IPX/SPX, AppleTalk,
DLC/LLC. For example, you should disable unused protocols to prevent printer access
using those protocols.
For network environments that use these protocols, see
Print Server.
Because it uses TCP/IP, the embedded Web server does not allow disabling TCP/IP.
Enable or disable various print services supported by the print server: port 9100, LPD
(Line Printer Daemon), IPP (Internet Printing Protocol), FTP (File Transfer Protocol).
Disable unused print services to prevent access through those services.
Enable or disable device discovery protocols supported by the print server:
SLP (Service Location Protocol).
If enabled (checked), the HP Jetdirect print server sends SLP packets, which are used
by system applications for automated discovery and installation.
If disabled (cleared), SLP packets are not sent.
If SLP uses multicast protocols, Multicast IPv4 must be enabled.
mDNS (multicast Domain Name System).
If enabled (checked), Multicast Domain Name System (mDNS) services are provided.
mDNS is typically used on small networks for IP address and name resolution (through
UDP port 5353) where a conventional DNS server is not used.
For mDNS operation, Multicast IPv4 must be enabled.
Multicast IPv4.
If enabled (checked), the print server will send and receive IP version 4 multicast
packets. If this parameter is disabled, other protocols that use multicast
protocols, such as mDNS and SLP, may also be disabled without notification.
Enable or disable Telnet access and the use of FTP to upgrade firmware on the print
server. Telnet and FTP are not secure protocols and device passwords may be
intercepted.
