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
Chapter 1.
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.
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.
Multicast IPv4.
If enabled (checked), the print server will send and
receive IP version 4 multicast packets.
