Your app can take advantage of the system’s built-in AirPrint technology to enable wireless printing of images, PDFs, and other content to compatible printers. While viewing printable content in an AirPrint-enabled app, people typically tap an action button in a navigation bar or toolbar and then tap a Print action to display a printer view. This view provides a list of available printers and any customizable options, such as the number of copies and page range, and provides a button to initiate printing.

Make printing discoverable. Enable printing through the system-provided Action button if your app has a toolbar or navigation bar. Users are familiar with this button and use it to print in other apps. If your app doesn’t have a toolbar or navigation bar, design a custom print button instead.

Enable printing only when it's possible to print. If there’s nothing onscreen to print or no printers are available, don’t show a Print action when someone taps the Action button. If your app implements a custom print button, disable or hide it when printing isn’t possible.

Provide printing options that add value. Think about the options people might want to specify when they print your content. Consider options for selecting a page range and requesting multiple copies. Enable additional options, such as front and back printing, if it makes sense and the printer supports them.
