Server-based TCP/IP configuration
In its factory-default state, the printer will first try BOOTP. If this fails it will then try DHCP. If this fails,
it will then obtain an IP address via AutoIP. In addition, a default IP address will not be assigned if a
network cable is not attached to the printer.
Default IP address configuration (AutoIP)
A default IP address will be assigned via the AutoIP protocol if the server based methods fail. When
DHCP or BOOTP fails to obtain an IP address, the printer uses a link-local addressing technique to
assign a unique IP address. Link-local addressing may be referenced as AutoIP. The IP address
assigned will be in the range of 169.254.1.0 to 169.254.254.255 (commonly referenced as
169.254/16), and should be valid. However, it can be further modified for your network using
supported TCP/IP configuration tools if necessary. With link-local addresses, subnetting is not used.
The subnet mask will be 255.255.0.0, and cannot be changed. Link-local addresses will not route off
the local link, and access to or from the Internet will not be available. The default gateway address
will be the same as the link-local address. If a duplicate address is sensed, the printer will
automatically reassign its address, if necessary, in accordance with standard link-local addressing
methods. The IP address configured on your printer may be determined by inspecting the network
configuration page for the printer. Since it may take some time for the server-based protocols to time
out, the AutoIP process can be sped up by disabling the BOOTP and DHCP services on the printer.
This can be done via a Web browser.
TCP/IP configuration tools
Depending on your printer and operating system, the printer can be configured with valid TCP/IP
parameters for your network in the following ways:
● Using Software—You can use the HP ToolboxFX software, or you can use the printer
Embedded Web server by entering the IP address in your Web browser.
● BOOTP—You can download the data from a network-based server using BOOTP (Bootstrap
Protocol) each time the printer is turned on. The BOOTP daemon, bootpd, must be running on a
BOOTP server that is accessible by the printer.
● DHCP—You can use Dynamic Host Configuration Protocol (DHCP). This protocol is supported
in HP-UX, Solaris, Red Hat Linux, SuSE Linux, Windows NT/2000/XP, NetWare and Macintosh
systems. (See your network operating system manuals to verify that your server operating
system supports DHCP.)
NOTE Linux and UNIX systems: For more information, see the BOOTPD man page. On HP?
UX systems, a sample DHCP configuration file (dhcptab) may be located in the /etc directory.
Since HP-UX presently does not provide Dynamic Domain Name Services (DDNS) for its
DHCP implementations, HP recommends that you set all printer lease durations to infinite.
This ensures that printer IP addresses remain static until such time as Dynamic Domain Name
Services are provided.
