Creating and printing a BufferedImage with Robot class

Question

I use class robot to create a bufferedImage of a screenCapture.
But all it keeps printing is a black box.
What am I missing here?
Dimension dim = mainPanel.getSize();
Robot robot = null;
try{ 
       robot = new Robot();
    final BufferedImage bufferedImage = robot.createScreenCapture(new Rectangle
                                           (mainPanel.getLocationOnScreen().x,
                                            mainPanel.getLocationOnScreen().y,
                                            dim.width,
                                            dim.height));
    catch( Exception e ){}     
        PrintUtilities.printImage(bufferedImage);Printing code
public class PrintUtilities implements Printable{
          private BufferedImage bufferedImage;
  public static void printImage(BufferedImage c) { 
          new PrintUtilities(c).print();
  public PrintUtilities( BufferedImage bufferedImage ){
         this.bufferedImage = bufferedImage;
  public void print(){
         PrinterJob printJob = PrinterJob.getPrinterJob();
         printJob.setPrintable(this);
           if (printJob.printDialog())
            try {
                  printJob.print();
                  System.out.println("calling printjob " );
            catch(PrinterException pe)
                   System.out.println("Error printing: " + pe);
public int print(Graphics g, PageFormat pf, int pageIndex){
             Graphics2D g2d = (Graphics2D)g;
             int imageWidth = bufferedImage.getWidth(); //width in pixels
             int imageHeight = bufferedImage.getHeight(); //height in pixels
             g2d.drawImage( bufferedImage, 0, 0, (int)pageWidth, (int)pageHeight, null );
             return Printable.PAGE_EXISTS;
          }

Ok, day 4 of working on this. Dukes are still up for grabs.
I created a small pop up frame in the print method of the print Utilities class to display the buffered image, worked fine. So the problem seems to be in the drawImage()
Someone has got to have a clue as to why this just printing a black box
The call to the print class:
PrintUtilities.printImage(bufferedImage);
The entire print class:
import java.awt.*;
import javax.swing.*;
import java.awt.print.*;
import java.awt.image.BufferedImage;
  public class PrintUtilities implements Printable{
          private BufferedImage bufferedImage;
  public static void printImage(BufferedImage c) { 
          new PrintUtilities(c).print();
  public PrintUtilities( BufferedImage bufferedImage ){
         this.bufferedImage = bufferedImage;
  public void print(){
         PrinterJob printJob = PrinterJob.getPrinterJob();
         printJob.setPrintable(this);
           if (printJob.printDialog())
            try {
                  printJob.print();
            catch(PrinterException pe)
                   System.out.println("Error printing: " + pe);
  public int print(Graphics g, PageFormat pf, int pageIndex) throws PrinterException {
     Graphics2D g2d = (Graphics2D)g;
     int panelWidth    = bufferedImage.getWidth(); //width in pixels
     int panelHeight   = bufferedImage.getHeight(); //height in pixels
     double pageHeight = pf.getImageableHeight(); //height of printer page
     double pageWidth  = pf.getImageableWidth(); //width of printer page
     if( pageIndex >= 1 ){
          return Printable.NO_SUCH_PAGE;
            // shift Graphic to line up with beginning of print-imageable region
      g2d.translate(pf.getImageableX(), pf.getImageableY());
      g2d.drawImage( bufferedImage, 10, 10, (int)pageWidth, (int)pageHeight, null );
      return Printable.PAGE_EXISTS;
}// close print class.
