I just bought an new MacPro. Come to find out my old printer (hp photosmart 7350) is no longer supported in Leopard. So I bought a new Canon Pixma ip4500. Turns out printing with bonjour over an airport is not supported in Leopard. My favorite thing was that Canon puts in small print on their driver download page that "Mac Air" printing was not supported. Who calls it "Mac Air" anyway? And why did they decide to hide it? So a fool would buy the printer and find out later it wasn't fully supported. What a Scam. What the h*** is wrong with Apple that they have to break every d**n thing with their worthless updates? Hello Apple! Wake up! Are there any printers in this world that works properly with Leopard?
