How the printer obtains an IP address during normal operation
When the printer is initially installed, it has no IP address. The address is
shown as
0.0.0.0. When the printer is turned on, it attempts to obtain an
IP address through RARP and BOOTP. If successful, the printer retains this
address in nonvolatile memory and continues to use it unless it receives a
different address from RARP or BOOTP when it is restarted.
When the IP address is set through the Apple Printer Utility for the Mac OS,
the Apple LaserWriter Utility for Windows, or
telnet, the printer no longer
makes an RARP or BOOTP request when restarted. An IP address set in this
manner is called a permanent address. For more information on using these
utilities, see Appendix A.
If the IP address is set through
ping assignment (described below), the
printer attempts to obtain an address through RARP and BOOTP when
turned on. If the printer does not receive configuration information through
RARP and BOOTP, the printer uses an address of
0.0.0.0.
To disable RARP and BOOTP requests completely, set the IP address
permanently through telnet or one of the other utilities.
Printer IP address assignment, option A: Using
ping
assignment
Any UNIX administrator with superuser privileges can use the ping
assignment method to assign the printer’s IP address. ping does not store
the IP address in the printer’s nonvolatile memory. You have to set the IP
address with
ping after each restart of the computer, or set the IP address
permanently with
telnet.
Note: This method works only when the printer has no IP address. If
you’ve already set the printer’s IP address, you cannot change it by using
this method.
1 Turn on the printer and save the startup page that it prints.
2 Log in as root to any UNIX workstation on the same subnet as the printer.
