Cups error: Unable to connect to cupsd: Connection refused

Cups doesn't seem to want to work since I transitioned my machine to systemd - although that may be a red herring.

I can start it via

systemctl start cups

and the web interface is available, although there are errors.  For example, the admin tab simply displays

Internal server error

and the printer tab shows:

Unable to get printer list:
Connection refused 

When I look in the log I can see

[CGI] Unable to connect to cupsd: Connection refused

If I enable the daemon with

systemctl enable cups.service

then it returns without errors - although I'm still getting the problems mentioned above - if that makes sense?

If I try and enable it with

systemctl enable cupsd.service

then it returns

Failed to issue method call: No such file or directory

The printer is connected and switched on! wink

Any ideas?

BTW - if it makes any difference, the printer is connected by wifi and has worked perfectly well for a while now.

Nevermind - rebooting the server fixed it!

I have the same problem, but after restarting cups for several times, the problem still didn't go away. Printing worked fine yesterday, today suddenly it won't.

Re: Cups error: Unable to connect to cupsd: Connection refused

The BrowseOrder directive (used in /etc/cups/cupsd.conf) stopped working for me after the last update I ran.  Removing it allowed cups to start properly.

What is the output from running:

systemctl status cupsd

That should identify any problems.

Re: Cups error: Unable to connect to cupsd: Connection refused

I'm having the same problem. I just installed cups (never used my printer with my arch box yet) but I can't connect to the cups server.
