Other Protocols
Item
Description
Enable Print Protocols
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
Introducing the HP Jetdirect Print
Server
.
Because it uses TCP/IP, the embedded Web server does not allow disabling TCP/IP.
Enable Print Services
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 Device Discovery
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.
Bonjour
.
If enabled (checked), Bonjour services are provided. Bonjour is typically used on for IP
address and name resolution (through UDP port 5353) where a conventional DNS server
is not used.
For Bonjour 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
Bonjour and SLP, may also be disabled without notification.
Enable Management Protocols
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.
Enable or disable RCFG, a remote IPX configuration protocol used by older management
tools to configure Novell NetWare parameters. Disabling RCFG does not affect direct mode
printing using IPX/SPX.
Disabling Telnet, FTP firmware upgrades, and RCFG is recommended.
802.1x Authentication
(Full-featured print servers only) This page allows you to configure 802.1X authentication settings on
the Jetdirect print server as required for client authentication on your network. In addition, you can reset
the 802.1X authentication settings to factory-default values.
CAUTION
Use caution when changing the 802.1X authentication settings; you may lose
your connection
. If communication with the printer/MFP device is lost, you may need to reset
the print server to a factory-default state and then reinstall the device.
