[JAVA2D] printing text and jtable

[java2d]

hello
i try to print a jtable and some text before and after my jtable. printing the 
jtable is ok, and some text after too. but i don't really understand the code 
(took from 
http://java.sun.com/developer/onlineTraining/Programming/JDCBook/advprint.html 
) i'd like to shift the jtable below some text.
someone has an idea please
(excuse my english )

    code:


        public int print(Graphics g, PageFormat pageFormat, int 
pageIndex)throws PrinterException 
            {
                Graphics2D g2 = (Graphics2D)g;
                g2.setColor(Color.black);
                //taille de la police
                int fontHeight = g2.getFontMetrics().getHeight();
                System.out.println(fontHeight);
                int fontDescent = g2.getFontMetrics().getDescent();
                System.out.println(fontDescent );
                
                // laisser de l'espace pour le numero de page
                //hauteur de la page 
                double pageHeight = pageFormat.getImageableHeight() - 
fontHeight;       
                System.out.println("pageHeight"+pageHeight );
                //largeur  de la page
                double pageWidth = pageFormat.getImageableWidth();
                System.out.println("pageWidth"+pageWidth );
                //largeur du tableau
                double tableWidth = 
(double)jTable2.getColumnModel().getTotalColumnWidth();
                System.out.println("tableWidth "+tableWidth );
                double scale = 1;
                //si lengthtableau est plus large que la page, on redimensionne
                if (tableWidth >= pageWidth) 
                {       
                    scale = pageWidth / tableWidth;
                    System.out.println("scale "+scale );
