[Touch-packages] [Bug 1099184] Re: Avahi reports IPv6/IPv4 and "dnssd" CUPS backend only tries IPv6, no IPv4 fallback
This is a bug in CUPS, CUPS needs to remember the address family of the advertised service (and preferably the interface ID). Avahi does know this interface and does provide it in the API responses to CUPS, but it's currently not using it.

Hi Nim (nimpetro), You've added a comment to an existing bug, which dopes not appear to be related to the problem you are having. This bug is about network issues with CUPS connecting to printers and not related to the page print formatting being incorrect. Please either open a new bug for your issue or seek support through our forums or another public resource. You can find a list of such community support resources here (load the page then click "Find community support") https://www.ubuntu.com/support/community-support I would suggest they might be a better place to start than a new bug. Off hand, if I had to guess I would suggest checking your page size is set correctly when printing, it's possible it does not match your actual paper. Not sure about the 90 degree rotation please. But please don't reply to that guess in this bug and take information about that to a new thread on the forums/discourse.

I have a Canon iX6820 printer. I have updated recommended driver for Ubuntu Linux. That was in Linux Mint 17.3. The printer worked flawlessly. I upgraded to Linux Mint 18.2 and reinstalled the same driver. When I print a landscape print job, generated in LibreOffice Writer on legal paper, the text prints only the center of the text and rotated 90 degrees and at the top of the page. If I generate a .pdf of the page, it prints landscape in the center of a portrait page with the whole thing shrunk to fit. Not good unless I read it with a magnifying glass. https://www.printererrorrepair.com/canon-customer-service/ -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to avahi in Ubuntu. https://bugs.launchpad.net/bugs/1099184 Title: Avahi reports IPv6/IPv4 and "dnssd" CUPS backend only tries IPv6, no IPv4 fallback Status in avahi package in Ubuntu: Confirmed Bug description: lsb_release -rd Description:Ubuntu 12.04.1 LTS Release:12.04 - avahi-daemon 0.6.30-5ubuntu2 cups 1.5.3-0ubuntu6 Avahi for default publishes services also in IPv6 as in /etc/avahi/avahi-daemon.conf there is use-ipv6=yes At the same time services are listening on IPv4 addresses only. Cups is able to discover published printers via dnssd protocol but its ipp backend prints only on the IPv6 resolved address which does not answer and it does not try the IPv4 address.
