Allowing machines other than localhost access to CUPS?

Question

In relation to this question on printing, I have found that I cannot administer the CUPS instance from a different machine. Is it possible that CUPS is configured to accept jobs only from the local machine, also? Is there a way to configure CUPS to accept jobs from other machines on the network? What is it?

A test of setting up another machine to print raw to the server in question (using the lpd protocol, lpd://server/printqueue) does not seem to be working either. The server is Ubuntu 10.10.

I see the following entry in the cupsd.conf file which suggests that CUPS may only accept jobs locally:

# Only listen for connections from the local machine.
Listen localhost:631

Any help appreciated.

You are correct about that line. Change it to Listen 0.0.0.0:631 in order to have it listen on all IPv4-enabled interfaces.

This works for printing but not for web interface, which on remote access reports an "access denied" message. – jaegermeister Jul 10 '19 at 09:40

I addition to change interface on which CUPS is listening (as described above) you need to enable remote administration in CUPS web panel (in Administration tab)
