I installed the Pixma MG3220 on my desktop and my laptop with success using the CD ROM, because I don't have the WPS button. I can print wirelessly from both computers, with no problems. I am not able to print from iPods, iPhones or the iPad. I have no idea what I am doing wrong. All I keep getting is no airprinter available, even if I am right next to the router and the printer. Please help! Thanks!
