If you are lucky or unlucky enough to own an HP printer...
...they make an app for that. It will utilize any HP on a wireless network. This includes our HP laser printer that is connected via USB, but is set up to be shared wirelessly.
I'd give the app 3 stars. Mostly because it mostly works. 🙂
You have WAY more options than AirPrint...including paper type.
