Digging a little bit in the link https://bugs.archlinux.org/task/30975 it seems that the problem is just that the default IPP version has changed to 2.0 in cups 1.6. My strace confirms that, so i guess that the solution is to find a way to configure cups to use the IPP version 1.1. Unfortunately, this was changed in the code of libcups2, and I do not find how to modify this in a config file like cupsd.conf.
