not sure but i have a wireless hp that connect to my home network so its not in wifi mode and i downloaded print central app last night, and everythings working fine, i was shocked...found my printer and all....printing fool now
I am equally confused. I have a wifi HP photosmart c4580 printer which AirPrint is unable to detect but works great with HP iprint photo apps.
What I understand is that AirPrint works with any printer if the print task is routed through a computer. I do not have such setup at home and I am still looking out for option to be able to print directly to the wifi printer.
