Remarks

To a create print support extension, your app must declare a uap4:Extension element with the category windows.printSupportSettings in its package manifest that specifies the entry point of a background task. When the background task is activated, the IBackgroundTask.Run method receives an IBackgroundTaskInstance object. You can cast the TriggerDetails property of this object to a PrintSupportExtensionTriggerDetails object to get more details about the print support extension session.

For more information, see Print support app design guide.
