EX7750 on the network
When the EX7750 is connected to a network, it behaves as a networked PostScript
printer. The built-in Ethernet interface on the EX7750 supports the following
network protocols (rules that enable computers on a network to communicate with
each other):
•AppleTalk
•TCP/IP
TCP/IP stands for Transmission Control Protocol/Internet Protocol. The lpd
protocol is the standard TCP/IP printing protocol. The nbt protocol supports
Windows (SMB) printing. The SMTP (simple mail transfer protocol) is the
protocol that sends e-mail between servers. The SNMP (simple network
management protocol) manages complex networks. The port 9100 is the printer
server port number to publish print connections between the print server and a
remote computer. The IMAP (internet message access protocol) retrieves e-mail
messages. The POP3 (post office protocol) retrieves e-mail messages with or without
SMTP. The http (hypertext transfer protocol) is commonly used for Web pages on
the Internet and on intranets. The http also supports IPP printing.
In addition, the DHCP and BOOTP are used for assigning IP addresses
automatically. These are not shown in the diagrams in this chapter. For more
information, see “TCP/IP Setup options” on page 4-19.
• IPX/SPX (Novell)
IPX/SPX stands for Internetwork Packet Exchange/Sequenced Packet Exchange.
