Impresssion sous Java

Question

Voila je souhaiterais imprimer une interface graphique contenant plusieurs JPanel et le Pb est que je sais pas comment faire   :sad)  .
J'ai consulter deja plusieurs articles sur le sujet mais ils sont pas tres clairs, et quand je les tests ils m'impriment que les JPanel mais pas le texte qu'il y a dessus (ce qui est légèrement embetant). Si on pouvais me donner un coup de pouce ce serait sympa  :big)

Créer une classe comme celle çi :



import java.awt.*;
import javax.swing.*;
import java.awt.print.*;

/** A simple utility class that lets you very simply print
 *  an arbitrary component. Just pass the component to the
 *  PrintUtilities.printComponent. The component you want to
 *  print doesn't need a print method and doesn't have to
 *  implement any interface or do anything special at all.
 *  
 *  If you are going to be printing many times, it is marginally more 
 *  efficient to first do the following:
 *  
 *    PrintUtilities printHelper = new PrintUtilities(theComponent);
 *  

 *  then later do printHelper.print(). But this is a very tiny
 *  difference, so in most cases just do the simpler
 *  PrintUtilities.printComponent(componentToBePrinted).

public class PrintUtilities implements Printable {

  private Component componentToBePrinted;

  /** imprimer composant
   * @param c le composant
   */

  /** print method **/
  public void print() {
    PrinterJob printJob = PrinterJob.getPrinterJob();
    printJob.setPrintable(this);
    if (printJob.printDialog())

        printJob.print();
      } catch(PrinterException pe) {
        System.out.println("Error printing: " + pe);
      }
  }
  
  /** print method
   * @param g graphisme
   * @param pageFormat format
   * @param pageIndex index
   * @return valeur de retour de l'impression
   */

  public int print(Graphics g, PageFormat pageFormat, int pageIndex) {
    if (pageIndex > 0) {
      return(NO_SUCH_PAGE);
    } else {
      Graphics2D g2d = (Graphics2D)g;
      g2d.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
      disableDoubleBuffering(componentToBePrinted);
      componentToBePrinted.paint(g2d);
      enableDoubleBuffering(componentToBePrinted);
      return(PAGE_EXISTS);
    }
  }

  /** The speed and quality of printing suffers dramatically if
   *  any of the containers have double buffering turned on.
   *  So this turns if off globally.
   * @see enableDoubleBuffering
   * @param c composant
   */
  public static void disableDoubleBuffering(Component c) {
    RepaintManager currentManager = RepaintManager.currentManager(c);
    currentManager.setDoubleBufferingEnabled(false);
  }

  /** Re-enables double buffering globally.
   * @param c composant
   */
  
  public static void enableDoubleBuffering(Component c) {
    RepaintManager currentManager = RepaintManager.currentManager(c);
    currentManager.setDoubleBufferingEnabled(true);
  }
}


Ensuite tu n'as plus qu'à faire 
PrintUtilities pu = new PrintUtilities();
puis
pu.print(MaFrame); (ou monPanel,...)
