Hi,

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.

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

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.
