Работа с печатью в TWebBrowser

{
  TWebBrowser can use native IE API to print and do other things.
  Implement on a Form a TWebBrowser component, and a button to print.
  The code attached to this button is as follow :
}

procedure TForm.OnClickPrint(Sender: TObject);
begin
  WebBrowser.ExecWB(OLECMDID_PRINT, OLECMDEXECOPT_PROMPTUSER);
end;
