Line gets bolder, when printed with Flash 11.6

<Problem>

When I print it to paper or pdf/xps driver with flash player 11.6, the line gets bolder than before.

<Sample code>

-----------

private function init():void

{

    var w:Number = 200;

    var h:Number = 200;

    var s:Sprite = new Sprite();

    rawChildren.addChild(s);

    var g:Graphics = s.graphics;    

    g.lineStyle(10, 16711680, 1, false, "normal", "none");

    g.moveTo(100, 100);

    g.lineTo(300, 100);

    g.lineStyle(1, 255, 1, false, "normal", "none");

    g.moveTo(100, 200);

    g.lineTo(300, 200);

}

-----------

<Conditions>
This problem is reproducible with 11.6 (11.6.602.168, 171).
Not reproducible with 11.5.5.2.135, or before.

<Memo>

As far as I can see on screen (in flash player), the thickness of line is no difference between 11.6 and before. The problem is observed, only when I print it to paper or pdf/xps driver.
