Как распечатать decision grid?

procedure TForm1.Button2Click(Sender: TObject);
begin
  Printer.BeginDoc;
  try
    printer.canvas.moveto(100,100);
    SetMapMode( printer.canvas.handle, MM_ANISOTROPIC );
    SetWindowExtEx(printer.canvas.handle,
                   GetDeviceCaps(canvas.handle, LOGPIXELSX),
                   GetDeviceCaps(canvas.handle, LOGPIXELSY),
                   Nil);
    SetViewportExtEx(printer.canvas.handle,
                   GetDeviceCaps(printer.canvas.handle,
LOGPIXELSX),
                   GetDeviceCaps(printer.canvas.handle,
LOGPIXELSY),
                   Nil);
    grid.PaintTo( printer.canvas.handle, 100, 100 );
  finally
    printer.enddoc;
  end;
end;
