Well, let me try anyhow:</div><div><br></div><div>I recently recognized that my iOS 6 devices can not print to cups/avahi (up2date CentOS 5.9 box, CUPS 1.3.7 as said) while iOS 5 devices work without problem. After much googling I found out that iOS6 expects cups to support the urf file type (whatever that is, it seems to, for now, just send a pdf file and call it urf). Then I implemented this (in short, informed the clients that urf is avail): </div><div> <a href="http://thepoch.com/tumblr/get-linux-airprint-working-again-for-ios-6.html">http://thepoch.com/tumblr/get-linux-airprint-working-again-for-ios-6.html</a></div><div>with the following changes:</div><div>- Put the airprint.* files to /etc/cups</div><div>- in airprint.convs, replace pdftoraster with pdftops (pdftoraster filter doesn't exist here, airprint-generate.py otherwise fails)</div><div><br></div><div>and then figured from here:</div><div> <a href="http://ubuntuforums.org/showthread.phpt=2060594&p=12260809#post12260809">http://ubuntuforums.org/showthread.phpt=2060594&p=12260809#post12260809</a> </div><div>that the URF=none should be changed to URF=DM3.

On iOS5 everything still works fine, but on iOS6 it gets aborted with "Error".
