I'm using a TWebBrowser to display a gif image from a web-server.

It seems like it's no way to print the image that are displayed.

Is tehere a good solution for this.. Can I use some other component to print the image or to download it in the temp dir and print it from there....

have you tried printing like so (quoted from, http://members.home.com/hfournier):

Q: How do I Print?

A: There are a couple of ways to print. The first example works in IE 4.x and up, but you'll have to use the second example in IE 3.x:

var
  vaIn, vaOut: OleVariant;

...

WebBrowser.ControlInterface.ExecWB(OLECMDID_PRINT, OLECMDEXECOPT_DONTPROMPTUSER, vaIn, vaOut);

or

procedure TForm1.PrintIE;
var
  CmdTarget : IOleCommandTarget;
  vaIn, vaOut: OleVariant;
begin
  if WebBrowser1.Document <> nil then
    try
      WebBrowser1.Document.QueryInterface(IOleCommandTarget, CmdTarget);
      if CmdTarget <> nil then
        try
          CmdTarget.Exec( PGuid(nil), OLECMDID_PRINT, OLECMDEXECOPT_DONTPROMPTUSER, vaIn, vaOut);
        finally
          CmdTarget._Release;
        end;
    except
      // Nothing
    end;
end;

Note: If you're not using Delphi 3.02 or higher, you'll have to change

PGuid(nil)
to
PGuid(nil)^
. And you really should upgrade to 3.02, if you're using 3.0 or 3.01.
