    Welcome to Microsoft Q&A!

    If you want to print page in uwp app, you could refer to the following steps.

    1.Write a xaml page that contains a print button. The OnPrintButtonClick event informs the user of the print situation.

        <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">  
            <Button  Click="OnPrintButtonClick">Print</Button>         
            <TextBlock Text="It's a good day !"/>  

    2.Declare the PrintManager and PrintDocument, register for printing

    private PrintManager printMan;  
            private PrintDocument printDocument;  
            private IPrintDocumentSource  printDocumentSource;  
            protected override void OnNavigatedTo(NavigationEventArgs e)  
                // Register for PrintTaskRequested event  
                printMan = PrintManager.GetForCurrentView();  
                printMan.PrintTaskRequested += PrintTaskRequested;  
                // Build a PrintDocument and register for callbacks  
               printDocument = new PrintDocument();  
                printDocSource = printDocument.DocumentSource;  
                printDocument.Paginate += CreatePrintPreviewPages;   
                printDocument.GetPreviewPage += GetPrintPreviewPage;  
                printDocument.AddPages += AddPrintPages;  

    3.Handle the print process, achieve the PrintTaskRequested, CreatePrintPreviewPages, GetPrintPreviewPage, AddPrintPages event, you could refer to the official document to know detailed code of these event handler.
