(Printing)

Description

Depending on the usage of the CUPS daemon, listening on the network should be limited. If the daemon is used a local spooler, it should be configured to listen on localhost only.

How to solve

Adjust the line stating "Listen" in the cupsd.conf file. Alter it so it only listens on the localhost interface, if appropriate. Listen localhost:631
