Another print-question!!!!

I print my image like this....
Printer.Canvas.StretchDraw(200,200, Image1.Picture.Graphic);
However, the functionality seems to be depending on my printer´s resolution: If I change the resolution of the printer from 360 dpi to 180 dpi, the image changes location on the page, and size aswell. There must be some printer-independent procedure's in Delphi, but I have trouble finding them.
I run Delphi Developer 2.0
Thanks!!

You must read you'r printer resolution and then draw on good place. Delphi have not printer independent procedure.
Try GetDeviceCaps.

Try this, is example for GetDeviceCaps like mirek says:

procedure TForm1.Button1Click(Sender: TObject);
var
  ScaleX, ScaleY: Integer;
  R: TRect;
begin
  Printer.BeginDoc;  
  with Printer do
  try
    ScaleX := GetDeviceCaps(Handle, logPixelsX) div PixelsPerInch;
    ScaleY := GetDeviceCaps(Handle, logPixelsY) div PixelsPerInch;
    R := Rect(0, 0, Image1.Picture.Width * ScaleX,
      Image1.Picture.Height * ScaleY);
    Canvas.StretchDraw(R, Image1.Picture.Graphic);
  finally
    EndDoc;
  end;
end;
