It seems CUPS introduced a chicken and egg issue: If desktop toolkits use CUPS 1.6 APIs to get dynamic printers support they need CUPS 1.6 installed on end-users machines but CUPS 1.6 cannot be used on end-users machines until desktop toolkits use CUPS 1.6 APIs.
It seems one needs to do a "big jump" and upgrade both CUPS and the desktop toolkits at the same time. To prepare for such a "big jump" experienced users must test it in advance before usual end-users get it. To let users test it, I think we should have a new OBS project whereto CUPS 1.6 and other related packages can be submitted e.g. something like a "Printing:Playground" project to make the distinction obvious that "Printing" is meant for (relatively) stable stuff that can be used without expecting major issues in "real-world environments" (e.g. on SLE11) but in contrast "Printing:Playground" is meant for venturous testers who expect even unexpected issues. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to cups in Ubuntu. https://bugs.launchpad.net/bugs/1061069 Title: CUPS 1.6 has major incompatible changes. Do not use CUPS 1.6.1 on stable Ubuntu releases Status in “cups” package in Ubuntu: Fix Released Status in “cups” source package in Quantal: Fix Released Status in “cups” package in Suse: Confirmed Bug description: Drastic changes in CUPS 1.6.1 (non Apple feature removed mostly) are detrimental to Ubuntu users. We should wait until the missing features (like automatic appearing of remote CUPS queues) before to unleash the newer version to users. This means downgrading cups in Quantal.
