Configure network settings You might need to configure certain network parameters on the product. You can configure these parameters from the installation software, the product control panel, the embedded Web server, or management software, such as HP Web Jetadmin. For more information about supported networks and network configuration tools, see the HP Jetdirect Print Server Administrator's Guide. The guide comes with printers in which an HP Jetdirect print server is installed. TCP/IP Similar to a common language that people use to communicate with each other, TCP/IP (Transmission Control Protocol/Internet Protocol) is a suite of protocols designed to define the way computers and other devices communicate with each other over a network. Internet Protocol (IP) When information is sent across the network, the data is broken down into small packets. Each packet is sent independently. Each packet is encoded with IP information, such as the IP address of the sender and receiver. IP packets can be routed over routers and gateways: devices that connect a network with other networks. IP communications require no connection. When IP packets are sent, they might not arrive at their destination in the correct sequence. However, higher-level protocols and programs place the packets in the correct sequence, so IP communications are efficient. Each node or device that communicates on the network requires an IP address. Transmission Control Protocol (TCP) TCP breaks the data into packets and recombines them on the receiving end by providing a connectionoriented, reliable, and guaranteed delivery service to another node on the network. When data packets are received at their destination, TCP calculates a checksum for each packet to verify that the data is not corrupt. If the data in the packet has been corrupted during transmission, TCP discards the packet and requests that the packet be resent. IP address Every host (workstation or node) on an IP network requires a unique IP address for each network interface. This address is used to identify both the network and specific hosts that are located on that network. It is possible for a host to query a server for a dynamic IP address each time the product boots up (for example, using DHCP and BOOTP). An IP address contains four bytes of information, divided into sections that each contain one byte. The IP address has the following format: xxx.xxx.xxx.xxx NOTE: When assigning IP addresses, always consult the IP address administrator. Setting the wrong address can disable other equipment operating on the network or interfere with communications. Configure IP parameters TCP/IP configuration parameters can be configured manually, or they can be automatically downloaded by using DHCP or BOOTP each time the product is turned on. 78 Chapter 6 Network configuration ENWW

TCP/IP
Similar to a common language that people use to communicate with each other, TCP/IP (Transmission
Control Protocol/Internet Protocol) is a suite of protocols designed to define the way computers and
other devices communicate with each other over a network.
Internet Protocol (IP)
When information is sent across the network, the data is broken down into small packets. Each packet
is sent independently. Each packet is encoded with IP information, such as the IP address of the sender
and receiver. IP packets can be routed over routers and gateways: devices that connect a network with
other networks.
IP communications require no connection. When IP packets are sent, they might not arrive at their
destination in the correct sequence. However, higher-level protocols and programs place the packets
in the correct sequence, so IP communications are efficient.
Each node or device that communicates on the network requires an IP address.
Transmission Control Protocol (TCP)
TCP breaks the data into packets and recombines them on the receiving end by providing a connection-
oriented, reliable, and guaranteed delivery service to another node on the network. When data packets
are received at their destination, TCP calculates a checksum for each packet to verify that the data is
not corrupt. If the data in the packet has been corrupted during transmission, TCP discards the packet
and requests that the packet be resent.
IP address
Every host (workstation or node) on an IP network requires a unique IP address for each network
interface. This address is used to identify both the network and specific hosts that are located on that
network. It is possible for a host to query a server for a dynamic IP address each time the product boots
up (for example, using DHCP and BOOTP).
An IP address contains four bytes of information, divided into sections that each contain one byte. The
IP address has the following format:
xxx.xxx.xxx.xxx
NOTE:
When assigning IP addresses, always consult the IP address administrator. Setting the wrong
address can disable other equipment operating on the network or interfere with communications.
Configure IP parameters
TCP/IP configuration parameters can be configured manually, or they can be automatically downloaded
by using DHCP or BOOTP each time the product is turned on.
