Other
Use this tab to enable or disable various protocols supported by the print server for printing, print services, and management. The items are described in Other protocols.
Other protocols
|
|
|
|
|
| Select the print protocols to use: IPX/SPX, AppleTalk, or DLC/LLC. (Disable unused protocols to prevent access.)
|
| Because the embedded Web server uses TCP/IP, you cannot disable this protocol.
|
| NOTE:
|
On HP Jetdirect 635n print servers, all network protocols except TCP/IP are disabled by factory default.
|
|
|
|
| Select the print services to use: port 9100, LPD, IPP, FTP, or Web Services Print. (Disable unused print services to prevent access.)
|
|
|
|
| Select device discovery protocols supported by the print server:
|
| If enabled, the HP Jetdirect print server sends SLP packets, which are used by system applications for automated discovery and installation.
|
| If disabled, SLP packets are not sent.
|
| If SLP uses multicast protocols, you must enable multicast IPv4.
|
| If enabled, 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, you must enable multicast IPv4.
|
| If enabled, the print server sends and receives IP version 4 multicast packets. If disabled, other protocols that use multicast protocols (such as Bonjour and SLP), might be disabled without notification.
|
| WS-Discovery Microsoft Web Services Dynamic Discovery (WS Discovery) protocols on the print server.
|
|
|
|
| Indicates whether link local multicast name resolution (LLMNR) requests are responded to over IPv4 and IPv6.
|
|
| Enable Management Protocols
|
|
| Select the management protocols to use: Telnet, FTP Firmware Update, or RCFG. Telnet and FTP are not secure protocols and device passwords can be intercepted.
|
| 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.
|
| It is recommended that you disable Telnet, FTP firmware upgrades, and RCFG.
