Comment 7 for bug 1069671

Thanks for the reply Till, and for the enlightenment on the meaning of the browsing options. Now for your questions:

1. Yes, I have double-checked that I get the same IP every time (my MAC address is hard-linked on the DHCP server to always obtain the same fixed IP and reverse DNS entry). The server also has a fixed IP that did not change since my upgrade to 12.10.

2. Yes, it is correct -- I also double-checked. I have used an IP address to ensure that DNS is not the problem (see attachment #2) and the address is the correct one for the CUPS server.

3. Yes, the IP address of my client is within one of the IP ranges given in the "Allow" directive.
Unfortunately, I am afraid I cannot change the CUPS server settings here (e.g. to @LOCAL) -- it is a production print server in a medium-sized research institution network and all changes would have to go through the sysadmins, who are keeping permissions naturally tight.

4. Not for hosts on the internal /24 network -- from outside only SSH access through a bastion host is supported. But I tried printing from the internal network of course.

What strikes me most is that everything worked fine on 12.04 and the problem suddenly appeared only after my 12.10 install. According to the sysadmins, nothing was changed at the same time on the server or network side -- so I just assumed it was a subtle CUPS 1.6 change in client configuration I missed.
