Q: HP3630 and BT Home Hub 5

We recently installed a BT Homehub with a new HP airprint 3630 printer. All devices are on the same wi-fi network, the windows laptop can print wireless but none of the Apple devices show printers, on both IPhone 6 and Ipad air and air 2 show "no airprint printers found"

With the old Netgear router all was working okay??
