Print a picture of a web application in asp.net

Hello I have my web application but I want to give the possibility to download and Printer-friendly image attached to a form, I have no idea how to do because I'm obviously new to C # and asp.net . As I can start ?

i try with onserverclick but i don´t have idea with i do to communicate with printer is my question How communicate with printers controllers to print a image?

I implemented the following and I get an error with the printer, but I do not get no window available printers.

 protected void imprime_tiff(object sender, EventArgs e)
    {
        PrintDocument pd = new PrintDocument();
        pd.PrintPage += new PrintPageEventHandler(pqr);
        pd.Print();
    }


    void pqr(object o, PrintPageEventArgs e)
    {
        System.Drawing.Image i = System.Drawing.Image.FromFile("C:\\Users\\MaxImage\\Desktop\\firma6.png");
        Point p = new Point(100, 100);
        e.Graphics.DrawImage(i, p);
    }

and in my html i put the next

 <button name="printButton" id="printButton" type="button" class="btn btn-  default" onserverclick=" imprime_tiff" runat="server" >
                                Imprime
  </button>

You won't be able to interact directly with the printer from a web browser. PrintDocument is only for WinForms applications and won't work with web applications.

The client browser needs to trigger the printing either manually (File > Print...) or through interaction with the page such as clicking on a button after which you can trigger the print dialog using JavaScript - https://developer.mozilla.org/en-US/docs/Web/API/Window/print

You can control the rendering of your page to make it "printer friendly" using a print style-sheet, there is a thorough write up here: http://www.smashingmagazine.com/2011/11/24/how-to-set-up-a-print-style-sheet/
