How do you print?
We are using Apple AirPrint technology inside the app. You can either buy a HP wireless printer that is compatible with AirPrint or download Airprint Activator to enable AirPrint printer sharing on Mac’s.
You can also try Printopia for $20
The Netgear network management utility Genie also enables Airprint on any Mac or Windows PC. It's free and you do not need any Netgear devices.
Another option is to take a screenshot by pressing the home button + power button at the same time. A screenshot will be saved to your ‘Photos’ app, which you can use to print or email to yourself.
One user posted in that software called collobos works quite well too.
