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.
