Network Printing 6-13
SMTP
SMTP (Simple Mail Transfer Protocol) is a protocol for sending e-mail.
This protocol was originally used to send e-mail between servers; however,
currently client e-mail software use it to also send e-mail to servers using
POP.
SNMP
SNMP (Simple Network Management Protocol) is actually a set of protocols
for managing complex networks. SNMP works by sending messages to differ-
ent parts of a network. SNMP-compliant devices, called agents, store data
about themselves in Management Information Bases (MIBs) and return this
data to the SNMP requesters.
Port 9100
When printing through a network, TCP/IP port number 9100 can be used to
send raw data.
WSD print
Printing is possible using the WSD (Web Service on Devices) function
installed in Windows 7/Vista/Server 2008. A connection supports WSD,
detects the printer on the network automatically and connects. Specifying a
WSD printer when printing from Windows 7/Vista/Server 2008 allows printing
using Web service for communication.
