Remarks

Background task handlers can use local storage to save the PrinterName and EventData values of the PrintNotificationEventDetails class, so that the information can be used later by an app.

// Save the printer name and asyncUI xml
//
var keyPrinterName = "BA5857FA-DE2C-4A4A-BEF2-49D8B4130A39";
var keyAsyncUIXML = "55DCA47A-BEE9-43EB-A7C8-92ECA2FA0685";
var settings = Windows.Storage.ApplicationData.current.localSettings;

//
// The background task instance's activation parameters are available
// via Windows.UI.WebUI.WebUIBackgroundTaskInstance.current
//
var backgroundTaskInstance = Windows.UI.WebUI.WebUIBackgroundTaskInstance.current;

// Save data into a user-defined var, "settings" 
var details = backgroundTaskInstance.triggerDetails;
settings.values[keyPrinterName] = details.printerName;
settings.values[keyAsyncUIXML] = details.eventData;

// Save directly into PrintNotificationEventDetails
Windows.Devices.Printers.Extensions.PrintNotificationEventDetails = details;
