Printing without UIPrintInteractionController

i am developing a POS(point of sale)application.i am able to print successfully with the UIP开发者_如何学PythonrintInteractionController popover. however , when a printticket button is pressed on the screen it should directly print without having the print interaction popover. i am not sure if this can be possible.

can anyone suggest an alternative?

Thank You.

Good news, with iOS8 it is now possible to print without UIPrintInteractionController. See the WWDC 2014 video Adopting AirPrint. They specifically mention how useful this is for POS applications.

I've interacted with the iOS Printing API a bit, and I've never come across a way to print without using the UIPrintInteractionController. As an iOS device user, I'm not sure I'd want a way to print without my say-so, because then any old app could just start spamming my printer.
