How do I change a printer’s IP address in AIX?

The mappings of IP addresses to “lp” names are contained in the /etc/hosts configuration file. To change the IP address:

Log into your server as root user via Eterm or PuTTY
Edit the /etc/hosts file using vi:

vi /etc/hosts

Locate the entry for the printer(s) you wish to change
Make the change
Save the file and quit
