Cups - aaaargh, why is this so damn difficult?

(from /var/log/cups/error.log)

E [18/Nov/2011:14:38:23 +0000] Unable to open listen socket for
address [v1.::1]:631 - Address family not supported by protocol.
E [18/Nov/2011:14:38:23 +0000] Unable to set ACLs on root certificate
"/var/run/cups/certs/0" - Operation not supported
W [18/Nov/2011:14:38:53 +0000] [CGI] no socket to connect to
W [18/Nov/2011:14:38:55 +0000] [CGI] no socket to connect to

I do not understand these error messages, and a search does not bring up any solutions.

I am using cups-usblp with an Epson R200 and the 'new' driver profile. I am in the lp group.

I've been at this for a good few hours now on two different computers, and all my print jobs seem to be disappearing into the ether, despite the printer being detected and 'ready to print'. I had printing working last week (with plain cups), until I had to reinstall the printer because it got stuck on 'I/O error' and 'out of paper', since when it's no longer even detected with plain cups (with or without usblp module properly blacklisted the new way).

Could someone please give me a hint about what ACL is, or why there is 'no socket to connect to'? I'm about at the end of my tether with reinstalling cups and reading 5 year old gentoo forum posts.

I'm going outside now to try and calm down....
(apologies if this is in the wrong forum, I can't seem to see a more appropriate one through the red mist)

Edit: additional info: when I print, jobs appear as 'completed' on the cups admin page, but nothing is printed

Re: Cups - aaaargh, why is this so damn difficult?

My guess is that it's a permissions issue.  Can you print from root?
