Printer IP address assignment, option C: Using a RARP or BOOTP server
If your network has a RARP or BOOTP server on the same subnet as the
printer, you can use it to assign the IP address to the printer. Each time the
printer is turned on, it will automatically broadcast a request to RARP and
BOOTP servers, which will search a configuration file that maps the printer’s
built-in Ethernet address to the IP address that you assign.
IMPORTANT When you use RARP or BOOTP to assign the printer’s IP
address, the address is not stored permanently in the printer; consequently,
the RARP or BOOTP server must be available each time the printer is turned
on. If you want to store the address permanently in the printer’s nonvolatile
memory, you must set the address using any of the other methods described
in the previous or following sections. You may also store the address using the
TCP/IP Printer Configuration Utility described later in this chapter.
Your network documentation explains how to add the printer’s information to
the RARP or BOOTP configuration file.
For troubleshooting information about RARP and BOOTP, see Chapter 13.
