Question: If there’s AirPrint on the iPad, why do you need to buy Printopia?
Sam Says: Apple’s AirPrint is on the iPad and iPhone. You also need AirPrint on the printer itself. Most printers don’t support AirPrint, except for a few from HP and a couple from Canon. With Printopia installed on the Mac that’s connected to your printer, it makes any printer ‘AirPrint’ compatible.
