Brain freeze here.  Want to print a bitmap image to the printer canvas.  Using stretchdraw preserves the image's size, but prints in in the upper left hand corner of my doc.  Want to print it in the lower right hand corner (it's a barcode).  How can I print it there, and still keep it's original size?

thanks!

*** CODE BEGINS ***

  ScaleX, ScaleY: Integer;
  R: TRect;
begin
  with Printer do
  try
    ScaleX := GetDeviceCaps(Handle, logPixelsX) div PixelsPerInch;
    ScaleY := GetDeviceCaps(Handle, logPixelsY) div PixelsPerInch;
    R := Rect(0, 0, pBitmap.Width * ScaleX,
      pBitmap.Height * ScaleY);
    Canvas.StretchDraw(R, pBitMap);
  finally
    // nothing to do...yet
  end;

Sorry, slight mistake in the rect calculation....

 R:=Rect(PageWidth-pBitmap.Width * ScaleX, PageHeight-pBitmap.Height * ScaleY, PageWidth, PageHeight);

You may have some problems using PageWidth and PageHeight on some printers.
You should set some reasonable margins.
