Hello I am using a HP mobile 100 printer (L411a) with a HP E546A NFC/Wireless 1200w accessory it all worked fine on IOS 8.4 but now my device is on IOS 9.02 it has stopped working using Airprint (I don't think it's worked at all on IOS 9 I have even tried the ios 9.2 beta 5 update and still no joy. It does eventually print but takes around 15 mins to finish. I can't down grade the IPad as I never created a back up. But I have tried another device that is on IOS8.4 and that's fine. Does any one have a suggestion or do I just need to wait until either apple fix the bug or HP provide a firmware update
