When worlds collide – this is ostensibly an iOS tip, but it involves a Mac App, which should technically be an OS X tip, but hey – you probably know how to print from your Mac. It’s more likely that, like me, you have a printer that you use with your Mac and it isn’t one of them newfangled fancy AirPrint ones, neither. While AirPrint protocol has been around since iOS 4, I still haven’t bought a printer with it built in. Hey, mine works just fine, still!
If so, you can print from your iPhone or iPad to the printer connected to your Mac, using Printopia 2, a $20 Mac utility available from developer eCamm.
