Printing on non-standard page size

Question

Hi
I'm developing a class that prints a single page tiff on plotter. The page size is not standard. In most cases it is as wide as an A0 or as an A3 but the height has to be computed depending on the size of the image.
First question: how can I get the height in 72nds of an inch from a RenderedImage that contains the tiff? All I can get is its size in pixels, but I cannot get the resolution...
Second question: I tried to set the paper size in the pageformat with a new instance of Paper and also the imageableArea, but some part of the image are not printed and the image is deformed.
Have you got any suggestion?
Here's the piece of my class that actually prints. If you need, I can post the entire class
class PrintTif implements Printable {
public int print(Graphics g, PageFormat f, int pageIndex) {
      if (pageIndex >= 1) {
        return Printable.NO_SUCH_PAGE;
      if (renderedImage != null) {
              //  Converts the image size in 72nd of inch
              //  supposing it has 200x200 dpi (it is so, but I don't know why)
              double w = (double) renderedImage.getWidth() / 200.0 * 72.0;
              double h = (double) renderedImage.getHeight() / 200.0 * 72.0;
              // Set the papersize and the imageableArea at the sime size
              Paper paper = new Paper();
              paper.setSize(w, h);
              paper.setImageableArea(0,0,w,h);
              f.setPaper(paper);
              f.setOrientation(w > h ? PageFormat.LANDSCAPE :
                               PageFormat.PORTRAIT);
        // convert to a BufferedImage since I cannot write a RenderedImage for some reason
        BufferedImage good = new BufferedImage(
              renderedImage.getWidth(), renderedImage.getHeight(),
              BufferedImage.TYPE_BYTE_GRAY);
        Graphics2D g2dtemp = (Graphics2D) good.getGraphics();
        g2dtemp.drawRenderedImage(renderedImage, new AffineTransform());
        Graphics2D g2d = (Graphics2D) g;
        g2d.translate(f.getImageableX(), f.getImageableY());
        g2d.drawImage(good, 0, 0 , (int) f.getImageableWidth(),
                      (int) f.getImageableHeight(), 0, 0,
                      renderedImage.getWidth(),
                      renderedImage.getHeight(), null);
        return Printable.PAGE_EXISTS;
      else {
        return Printable.NO_SUCH_PAGE;
}

Hi,
According to the printers paper handling specifications, it's not able to handle A4 card.
