Comment 79 for bug 465916

Avahi is running and does not take 100% CPU:

root@ubuntu2:~# ps awux | grep avahi
root@ubuntu2:~# ps awux | grep avahi
avahi 739 0.0 0.0 32396 1944 ? S Dec13 0:00 avahi-daemon: running [ubuntu2.local]
avahi 740 0.0 0.0 32132 468 ? S Dec13 0:00 avahi-daemon: chroot helper

root@ubuntu2:~#

The "Share printers connected to this system" is checked. Protocols CUPS and DNS-SD.

What is the "shared bit for each print queue", and where do I set it up?

BTW, in the error log I saw the following error - is it related?
E [13/Dec/2011:21:18:58 +0200] Failed to update TXT record for HP_LaserJet_CM1415fn @ ubuntu2: -2

tcpdump on a different machine shows that cups on the oneiric (11.10) does not send the ipp broadcasts, whereas the natty (11.04) does.
05:53:51.444383 IP cmdesk09.local.ipp > 192.168.11.255.ipp: UDP, length 128

When debug mode on 11.10 is enabled, it looks like the broadcasts are sent (the lines repeat every 62 seconds):
D [14/Dec/2011:05:55:44 +0200] cupsdNetIFUpdate: "eth0" = 192.168.11.121:631

Notable, that at my home, cups print sharing on two computers with Ubuntu 11.10 works properly.
