Other Use this tab to enable or disable various protocols supported by the print server for printing, print services, and management. See Table 4.13. Table 4.13 Other Protocols (1 of 2) 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 Chapter 1. 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. 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. ENWW Using the Embedded Web Server 149
