You've updated your iPad and iPhone to iOS 4.2 and you want to print something... anything... but that printer hooked up to your Mac doesn't show up in the list of available devices. What can you do to make your iOS user experience complete?
As Mike noted in his AirPrint roundup last week, Netputing took note of the re-enabling process that Chris posted about and created a little hack called AirPrint Hacktivator (which now uses a different method than it did originally, see below). You can easily install it on your Mac and be printing like a maniac from your iOS 4.2 device in minutes.
