Remarks

PrintTaskSourceRequestedArgs is used to set the source of the content to be printed. Here is a code snippet from the UWP print sample that shows the SetSource method:

protected virtual void PrintTaskRequested(PrintManager sender, PrintTaskRequestedEventArgs e)
{
    PrintTask printTask = null;
    printTask = e.Request.CreatePrintTask("C# Printing SDK Sample", sourceRequested =>
    {
        // Print Task event handler is invoked when the print job is completed.
        printTask.Completed += async (s, args) =>
        {
            // Notify the user when the print operation fails.
            if (args.Completion == PrintTaskCompletion.Failed)
            {
                await scenarioPage.Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, () =>
                {
                    MainPage.Current.NotifyUser("Failed to print.", NotifyType.ErrorMessage);
                });
            }
        };

        // Call PrintTaskSourceRequestedArgs.SetSource
        sourceRequested.SetSource(printDocumentSource);
    });
}
