                PrintManager printmgr = PrintManager.GetForCurrentView();
                PrintDocument PrintDoc = null;
                PrintDocument printDoc;
                PrintTask Task = null;
                Windows.UI.Xaml.Controls.WebView ViewToPrint = new Windows.UI.Xaml.Controls.WebView();
                public Print_UWP()
                {
                    printmgr.PrintTaskRequested += Printmgr_PrintTaskRequested;
                }

                public async void PrintUWpAsync(string htmlSource)
                {
                    ViewToPrint.NavigateToString(htmlSource);
                    if (PrintDoc != null)
                    {
                        printDoc.GetPreviewPage -= PrintDoc_GetPreviewPage;
                        printDoc.Paginate -= PrintDoc_Paginate;
                        printDoc.AddPages -= PrintDoc_AddPages;
                    }
                    this.printDoc = new PrintDocument();
                    try
