Listening yes, advertising, no. After update and a reboot, the cupsd.conf was 
rewritten, my two lines telling it to listen on Localhost and the IP of the 
external NIC (tweo LISTEN entries in netstat) replaced with one *:631 line in 
the config file, and instead of listening one two IPs it now listens and 
advertised on *;631 (or to netstat).

Thank you for the thoughts, I am saving them in case I see this again, but I 
tried a boot off a Live-CD (CF13) and changed the "Localhost" to "*" and 
reloaded, and that worked as well.

About 40% of the tips I save in my notes are things that didn't solve the 
problem I had at the moment, but were useful against problems I can expect to 
have in the future.
