I use 1.7.2 CUPS clients with a 1.4.2 CUPS server.
To access to print menu in any applications, it was very slow (about 2 minutes), I have configured the version=1.1 option in /etc/cups client.conf, and now all works fine except system-config-printer so it may confirm that it doesn't respect the version=1.1 option in client.conf and still use IPP 2.0.
