Thats a four year old bug. The upshot is that Cups 1.7.2 cannot _automatically_ advertise printers with Avahi. I cannot infer much from the bug ticket but if I had to guess I'd say that the problem is lodged in the Political rather than the Software Engineering levels.
One option here is to downgrade cups back to 1.5.x. Another is to workaround the issue with a manual service file for each your printers. In my case this was easy solution since I'm only advertising a pair of printers. If you have to do this for 1000 printers my solution doesn't scale.
I basically put this into:
/usr/local/etc/avahi/services/hp-4000.service

To advertise my HP LaserJet 4000TN cups attached printer via Bonjour. My Mac's can all print to the devices.
Hope this is helpful.
