```
                Dim doc As New PdfDocument()
                Dim pgSt As New PdfPageSettings()
                pgSt.Size = PdfPageSize.A4
                pgSt.SetMargins(0.5, 0.5, 0.5, 0.5)

                Dim htmlLayoutFormat As New PdfHtmlLayoutFormat()
                htmlLayoutFormat.IsWaiting = False

                ' Dim htmlpath As String = "D:\Print-code\test3.html"
                Dim source As String = response.Content ' File.ReadAllText(htmlpath)
                doc.LoadFromHTML(source, True, pgSt, htmlLayoutFormat)

                doc.PrintSettings.PrintController = New StandardPrintController()
                doc.PrintSettings.PrinterName = printer
                'doc.PrintSettings.Copies = 2
                'Print all pages with default printer
                doc.Print()
