OpenSuse 12.2 ipad iOS6 airprint stops working

Hi All

I had my ipad printing via airprint to my printer. It stopped working when I upgraded to iOS6. The reason is that Apple has changed from pdf to urf.

I have been on the Internet and have found various solutions which I have tried. My ipad can now see my printer but when I print, the document does not appear in the print queue.

What is curious is that even though CUPS and avahi are used, the solutions differ slightly depending on the distribution?

So has anybody got iOS6 printing with CUPS and avahi on OpenSuse 12.2?

Thanks

I hope you don’t mind an answer almost a year after your query. After banging my head against the keyboard for many hours and reading a dozen sites, I discovered that the firewall defaults to blocking IPP printing. Since this machine is inside a network and behind another firewall, I’ve temporarily turned off the firewall until I can figure out what rules I need to add. So now my iOS6 devices print nicely to a networked printer. You can also change it to internal zone which opens all the ports.

I tried allowing udp/631 on source port but that isn’t enough. Neither is another rule for udp/631 on destination port.
Firewall rules don’t come easy to me so it will take me awhile to figure this out. The firewall log is too difficult for me to read.

Hopefully this will get you started.

For instance:


FW_SERVICES_EXT_TCP="ipp"
FW_SERVICES_EXT_UDP="ipp"

Or if you want to allow only one computer, do like this:


FW_TRUSTED_NETS="192.168.1.100,tcp,ipp    192.168.1.100,udp,ipp"

Thanks for these guidelines. I’ve only tried the gui in YaST so you have given me something else to investigate.

I did finally resolve my firewall problem, thanks to finding a post by Tsu. ipp requires both tcp & udp open, as is also shown by your posted code.
Once I added tcp/631 to my rules it worked very well.

Rgds, Jon

Ah, the GUI… It’s long since I used it. I edit directly the file
“/etc/sysconfig/SuSEfirewall2” (I thought you were doing it this way).
The comments are the same as in the GUI.

I find editing the file easier than using the firewall GUI. You have to
manually restart the firewall, the command is simply “SuSEfirewall2”.
