Printing resolutions, trees, resizing components & co

Question

Hi.
I've a little problem which grows bigger and bigger every day: I've to print a tree. Sound's easy, hm? That's not all, I have to use a template and there's a place marked where I've to put that tree (can be a component) but I'm not allowed to change template and I'm not the one adding the other components, just reponsible for trees.
Ok, now I managed that tree is displayed over more pages without cutting any objects at end of page but now I face other troubles: The tree is too big at all. So I've to resize this.
I was first wandering, why tree was that big and it is because a page is always rendered with 72dpi by default. First think I thought was to change printing resolution by setting page attributes:
    PageAttributes pageAttributes = new PageAttributes();
    int[] attributes = pageAttributes.getPrinterResolution();
    // using 150 dpi instead of 72 to make tree half sized
    attributes[0] = 150;
    attributes[1] = 150;
    pageAttributes.setPrinterResolution(attributes);
    PrintJob theJob = getToolkit().getPrintJob(this, Catalog.getString("Previewer"), null, pageAttributes);Works fine, but resizes everything, also header and footer and all other components which are already displayed in current size.
So I need something else.
I think the real resize happens in the WPrintGraphicsWrapper (yes, I'm using windows) where the AffineTransform for the WPrintGraphics is calculated and set.
I can't avoid this but I tried to set another scale for the graphics during painting by calling following method in the paint-method of the base components I want to resize:
  protected Graphics checkScaleGraphics(Graphics g, boolean rescale) {
    if (g instanceof Graphics2D) {
      // at preview g2d is received
      if (rescale) {
        ((Graphics2D)g).scale(((double)1/scaleFactor), ((double)1/scaleFactor));
      } else {
        ((Graphics2D)g).scale(scaleFactor, scaleFactor);
    } else {
      // trying to get 2D graphics object for scaling using reflect
      try {
        // get real graphics from wrapper
        Graphics2D d2Graphics = (Graphics2D)g.getClass().getMethod("getTarget", null).invoke(g, null);       
        if (rescale) {
          d2Graphics.scale(((double)1/scaleFactor), ((double)1/scaleFactor));
        } else {
          d2Graphics.scale(scaleFactor, scaleFactor);
      } catch(Exception e) {
        System.out.println("Exception: "+e); // for testing, no exception handling
    return g;
  }Using reflect is rather slow but code must be compileable on sun too.
However it doesn't work at all. The components get resized but the nodes where irrecognizable, especially text looks cruel.
Also using reflect is very slow and code must be compileable on sun also.
Has anybody experience with this or knows a good way how to print a tree at all?
Thanks in advance
