iOS printing without AirPrint I have HP Laserjet 1020 connected to Airport Express and, after installing HP drivers, can print from MacBook Air. But there is no way to print from iOS devices because they need AirPrint compatible printer. Firstly, i installed handyPrint on mac, and everything was fine, but it works only when mac is on. So I tried and Printer Pro Lite application on iPhone. App can see printer but doesn't print anything. So I try to understand is there any possible way to tune my printer as AirPrint printer to print whenever I want? Or maybe install the right app on iPhone which can print?
Printer Pro won't solve the problem because


  Printer Pro is the application that lets you wirelessly print from the iPhone. It can print directly to many Wi-Fi printers and to any printer attached to your Mac or PC via helper application installed on your computer.


If you search for "HP print" in the App Store, there are quite a lot of hits. HP All-in-One Printer Remote looks kind of helpful (but I can't test it myself).
