Printing from IPad App

Just wondering if there is a way to add functionality to my IPad app to print.

I know there seems to be a few apps out there now that allow you to print to a printer fro开发者_如何转开发m your ipad but I just want to have a print button within my app that prints to a device.

Is this possible?

Thanks

Yup, with AirPrint in iOS 4.2.

Not many printers are supported, but you can proxy through your Mac.
