3. Miscellaneous: Shows information about more advanced network settings.
• Port 9100 : The printer supports raw IP printing through TCP Port 9100. This
HP-proprietary TCP/IP port on the printer is the default port for printing. It is
accessed by HP software (for ex ample, the HP Standard Port).
• LPD : Line Printer Daemon (LPD) ref ers to the protocol and programs
associated with line-printer spooling  services that may be installed on various
TCP/IP systems.
NOTE: The LPD functionality can be used with any host implementation of
LPD that complies with the RFC 1179 document. The process for
configuring printer spoolers, however, might differ. See your system
documentation for information about configuring these systems.
• Bonjour : Bonjour services (which use mDNS, or Multicast Domain Name
System) are typically used on small networks for IP address and name
resolution (through UDP port 5353), where a conventional DNS server is not
used.
• SLP : Service Location Protocol (SLP) is an Internet standard network protocol
that provides a framework to allow networking applications to discover the
existence, location, and configuration of networked services in enterprise
networks. This protocol simplifies discovery and use of network resources such
as printers, Web servers, fax machines, video cameras, files systems, backup
devices (tape drives), databases, directories, mail servers, calendars.
• Microsoft Web Services : Enable or disable the Microsoft Web Services
Dynamic Discovery (WS Discovery) protocol s or Microsoft Web Services for
Devices (WSD) Print services supported  on the printer. Disable unused print
services to prevent a ccess through those services.
NOTE:For more information about WS Discovery and WSD Print, visit
www.microsoft.com.
•SNMP : SNMP (Simple Network Managemen t Protocol) is used by network
management applications for printer management. The printer supports
SNMPv1 protocol on IP networks.
• WINS : If you have a Dynamic Host Configuration Protocol (DHCP) server on
your network, the printer automatically ob tains its IP address from  that server
and registers its name with any RFC 1001 and 1002-compliant dynamic name
services as long as a WINS server IP address has been specified.
4. Connected PC(s) : Lists the computers connected to this printer, as well as the last
time these computers  accessed the printer.
