samba - Jul 2011 - printing = cups issue ....

Using samba 3.4.9 and cups 1.4.3 

I have "printing = cups", but for some reason samba is not picking up
the cups printers or creating the printers share.

The problem is obviously this, from the samba logs: 
[2011/03/28 14:09:43, 0] printing/print_cups.c:103(cups_connect) 
Unable to connect to CUPS server localhost:631 - Connection refused 

However, cupsd is most certainly listening on localhost:631, and an lpstat -a -h
localhost gives a list of printers. Why is samba not able to communicate with
it? I've turned off all security measures (apparmor, etc.) but still no.

Please provide full logs with log level = 10 configured in smb.conf.
Also, does anything relevant appear in the cups access log?

Hmm. In my case lpstat always connects to the local cupsd via the Unix
domain socket (e.g. /var/run/cups/cups.sock), even with the -h option
specified. Looks like it's due to /etc/cups/client.conf configuration.
You may want to check with strace whether yours is doing the same.
