TCP/IP environment

4.1

A TCP/IP network provides you with various protocols for using printing 
devices and managing various types of networked devices.

In this chapter, you will learn which management protocols are available 
in TCP/IP network environments, and how to print via your network print 
server using TCP/IP protocol.

Before beginning to print documents via your network printer, you need 
to check or configure some parameters using management protocols.

Dynamic Host Configuration Protocol (DHCP) is a communication 
protocol enabling network administrators to centrally manage and to 
automate the assignment of IP addresses in a network. In an IP network, 
each device needs a unique IP address. DHCP lets a network 
administrator supervise and distribute IP addresses from a central point 
and automatically sends a new IP address when a device is plugged into 
a different place in the network. 

Bootstrap Protocol (BOOTP) is UDP/IP-based protocol which allows a 
booting host to configure itself dynamically and without user supervision. 
BOOTP provides means to notify a host of its assigned IP address, the 
IP address of a boot server host, and other configuration information, 
such as the local subnet mask, the local time offset, and the addresses 
of default routers. Addresses of various Internet servers can also be 
transferred to a host using BOOTP. 

DHCP is active by factory default on your network print server. After boot 
up, the network print server will get an IP address automatically from the 
DHCP server, if one exists. To set an IP address manually, see page 2.2.

To enable or disable DHCP/BOOTP, use one of the following methods:

• Web Image Monitor SP 3300 Series: Select Network Settings > 

TCP/IP and select DHCP or BOOTP from the IP Address Assignment 
Method list.

Hypertext Transfer Protocol (HTTP) is an application layer protocol for 
distributed, collaborative, hypermedia information systems. It is a 
generic, stateless protocol which can be used for many tasks beyond its 
use for hypertext, such as with name servers and distributed object 
management systems. You are using HTTP when you connect your 
network printer via a web browser.

The Network Printer Card has a built-in web server, Web Image Monitor 
SP 3300 Series. You can configure and manage your network print 
server through Web Image Monitor SP 3300 Series using HTTP over 
TCP/IP.

Simple Network Management Protocol (SNMP), which is part of the 
TCP/IP protocol suite, is an application layer protocol that facilitates the 
exchange of management information between network devices. It 
enables network administrators to remotely monitor and configure 
network devices, find and solve network problems, and plan for network 
growth.

Network devices are monitored and controlled using four basic SNMP 
commands: 

• read: is used by a Network Management server to monitor network 

devices. The server examines different variables that are maintained 
by the devices.

• write: is used by a Network Management server to control managed 

devices. The server changes the values of variables stored within the 
devices.

• trap: is used by network devices to asynchronously report events to a 

Network Management server. When certain types of events occur, a 
device sends a trap to the specified server.

• Traversal operations: are used by a Network Management server to 

determine which variables a network device supports and to 
sequentially gather information in variable tables, such as a routing 
table.

To access your network print server using SNMP, Community Name/
Access Permission pair must be properly specified. There are two 
access permission: read and write.

Assign the IP addresses of trap hosts and community names (IP 
addresses) of network devices in Web Image Monitor SP 3300 Series; 
select Network Settings > SNMP. 

Web Image Monitor SP 3300 Series accesses, configures, and manages 
network devices using SNMP. You can use other MIB (Management 
Information Base) browser software, which allows you to access 
management information gathered from network devices.
