AirPrint have some issues with iOS 8.1.3
I used airprint in iOS 7 with no issues. But when i updated my iPhone/iPad to iOS 8 it will not work all the time. Sometimes it will work and most of the time i should restart the printer to connect to the iPhone/iPad. AirPrint is having issues with both my iPhone and iPad (iOS 8). Both the devices are connected to the same network.
Printer Used: HP Photosmart B110 Series
iPhone 5, iOS 8.1.3
