IPP

IPP (Internet Printing Protocol) is a protocol for end users’ most common

printing situations over the Internet. It allows users to find out about a printer’s

capabilities, submit print jobs to a printer, determine the status of the printer

or print job, and cancel a previously submitted print job.

For more information on using IPP, See “Printing via IPP (Internet Printing

Protocol) – Windows Server 2003/XP/2000” on page 94.

LPD/LPR

LPD/LPR (Line Printer Daemon/Line Printer Request) is a platform-

independent printing protocol that runs over TCP/IP. Originally implemented

for BSD UNIX, its use has spread into the desktop world and is now an

industry standard.

Port 9100

When printing through a network, TCP/IP port number 9100 can be used to

send raw data.

SLP

Traditionally, in order to locate services on the network, users had to supply

the host name or network address of the machine providing the desired ser-

vice. This has created many administrative problems.

However, SLP (Service Location Protocol) simplifies the discovery and use of

network resources such as printers by automating a number of network ser-

vices. It provides a framework that allows networking applications to discover

the existence, location, and configuration of networked services.

With SLP users no longer need to know the names of network hosts. Instead,

they need to know only the description of the service they are interested in.

Based on this description, SLP is able to return the URL of the desired

service.

Unicast, Multicast, and Broadcast

SLP is a unicast and a multicast protocol. This means that messages can be

sent to one agent at a time (unicast) or to all agents (that are listening) at the

same time (multicast). However, a multicast is not a broadcast. In theory,

broadcast messages are “heard” by every node on the network. Multicast
