Configuring IP parameters

TCP/IP configuration parameters (such as IP address, subnet mask, default gateway) can be configured on the printer in a variety of ways. These values can be configured manually (for example, through Telnet, the embedded Web server, the arp and ping commands, and HP management software), or they can be automatically downloaded using DHCP or BOOTP each time the printer is turned on.

When powered on, a new printer that is unable to retrieve a valid IP address from the network will automatically assign itself a default IP address. The default IP address will depend on the type of network to which the printer is connected. On a small private network, a technique called link-local addressing is used to assign a unique IP address in the range of to, which should be valid. On a large or enterprise network, a temporary address of will be assigned until it is properly configured for your network. The IP address configured on your printer may be determined by inspecting the printer Configuration page.

Dynamic Host Configuration Protocol (DHCP)

DHCP allows a group of devices to use a set of IP addresses that are maintained by a DHCP server. The device or host sends a request to the server, and if an IP address is available, the server assigns it to that device.


BOOTP is a bootstrap protocol used to download configuration parameters and host information from a network server. BOOTP uses UDP for its transport. In order for devices to boot and load configuration information into RAM, they must communicate through the bootstrap protocol BOOTP as a client with their server.

To configure the device, the client broadcasts a boot request packet containing at least the hardware address of the device (printer hardware address). The server answers with a boot reply packet containing the information the device needs to configure.
