Printing from System.Windows.Forms.WebBrowser RRS feed

  • Question

  • Hi,

       I have a windows form (not WPF) application with a System.Windows.Forms.WebBrowser control. I have text marked up in  the control with background highlighting, underlining and borders for specific characters (see below for image). I would like users to be able to print and retain all the formatting. I tried using the browser's print with RightClick-Print. That does not print the highlight colors. I tried copying and pasting into Word. That does not print the borders. So then I cobbled together the following code (which I don't quite understand):

     private void printBowserButton_Click(object sender, EventArgs e)
            {
                System.Drawing.Printing.PrintDocument printDoc = new System.Drawing.Printing.PrintDocument();
                printDoc.PrintPage += PrintDoc_PrintPage;
                printDoc.Print();
            }
            private void PrintDoc_PrintPage(object sender, System.Drawing.Printing.PrintPageEventArgs e)
            {
                Bitmap image = TakeScreenShot(startStopRegionBrowser);
                e.Graphics.DrawImage(image, e.MarginBounds.Left, e.MarginBounds.Top);
            }
    
            private Bitmap TakeScreenShot(Control control)
            {
                Bitmap tmpImg = new Bitmap(control.Width, control.Height);
                using (Graphics g = Graphics.FromImage(tmpImg))
                {
                    g.CopyFromScreen(
                        control.PointToScreen(new Point(0, 0)),
                        new Point(0, 0),
                        new Size(control.Width, control.Height));
                }
                return tmpImg;
            }

    This works and prints an image of the portion of the webbrowser control that is visible when the print button is clicked. I would really like to print the complete document. Any suggestions?

    I am programming in C# using Visual Studio Enterprise 2017 with .Net Framework 4.6.1. I am running Windows 10. My default Web Browser is IE 11 (does that matter?).

    If this is the wrong forum, can you please point me in the right direction?

    Thanks!

    Ethan
