drawing not printed

Hi,
I have a form with some drawing on it (using LineTo();) and I'd like to print it, but when I call form1.print, I see just the empty form without the lines. Why is that and how can I resolve it?

thanks in advance

Hi, try use function
GetFormImage(): TBitmap;

didn't work, here is the source:

procedure TForm1.printfrm;
var FormImage: TBitmap;
begin
  FormImage:=GetFormImage;
  print;
end;

Now I see. You just must repaint all your lines in OnPaint event, like this:

procedure TForm1.Button2Click(Sender: TObject);
begin
    Print;
end;

procedure TForm1.FormPaint(Sender: TObject);
begin
    Canvas.MoveTo(0,0);
    Canvas.LineTo(100,100);
end;
