pitti, I remember that the old CUPS broadcasting (by CUPS itself,
without Avahi/Bonjour) was happening only every 30 sec. The new
Avahi/Bonjour method seems to be faster. But note that for testing I
have run the following script
----------
sudo stop cups-browsed
sudo stop cups
sudo stop avahi-daemon
sleep 10
sudo start avahi-daemon
sudo start cups
sudo start cups-browsed
watch lpstat -v
----------
Now I do not know whether avahi-daemon is creating a cache file to
conserve the cached items while being shut down and restarted later.
With this script the queues appear in ~4 sec.
