GEN003900 - The hosts.lpd file (or equivalent) must not contain a '+' character - 'Listen'

Information

Having the '+' character in the hosts.lpd (or equivalent) file allows all hosts to use local system print resources.

Solution

Configure cups to use only the localhost or specified remote hosts.

Procedure:
Modify the /etc/cups/cupsd.conf file to 'Listen' only to the local machine or a known set of hosts (i.e., Listen localhost:631).
Modify the /etc/cups/cupsd.conf file '<Location />' element to 'Deny From All' and 'Allow from 127.0.0.1' or allowed host addresses.

Restart cups:
# service cups restart
