Printing black background on paper, instead of actual image

Question

hi,
i am having a JPanel with some photos drawn on it using g.drawImage(..) method, for printing. while running the program the panel is showing fine on the screen. since in my room as i dont have a printer, i am printing with adobe printer in which the content to be printed will be saved as pdf file.
Even the created pdf file while printing is showing perfectly what is supposed to be printed. but when i tried the same program and asked to print on real printer, strangely only a large full black background is printed on paper instead of the image.
plz explain why such thing is happening.
thanx.

Here is sample code based on your description. Maybe you find some hints in it to help you.
import java.awt.*;
import java.awt.event.*;
import java.awt.print.*;
import javax.swing.*;
public class PrintPanel extends JFrame {
    public PrintPanel() {
        initComponents();
    private void initComponents() {
        toolBar = new JToolBar();
        printB = new JButton();
        panel = new MyPanel();
        setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
        setTitle("Print Panel");
        toolBar.setFloatable(false);
        printB.setText("Print");
        printB.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent evt) {
                printBActionPerformed(evt);
        toolBar.add(printB);
        getContentPane().add(toolBar, BorderLayout.NORTH);
        getContentPane().add(panel, BorderLayout.CENTER);
        Dimension screenSize = Toolkit.getDefaultToolkit().getScreenSize();
        setBounds((screenSize.width-375)/2, (screenSize.height-480)/2, 375, 480);
    private void printBActionPerformed(ActionEvent evt) {
        PrinterJob pj=PrinterJob.getPrinterJob();
        pj.setPrintable((Printable)panel);
        try{
            pj.print();
        }catch (PrinterException ex) {
            ex.printStackTrace();
    public static void main(String args[]) {new PrintPanel().setVisible(true);}
    private JButton printB;
    private JToolBar toolBar;
    private JPanel panel;
    class MyPanel extends JPanel implements Printable{
        MyPanel() {
            Toolkit T=this.getToolkit();
            img=T.getImage("c:\\javalogo.gif");
            MediaTracker mediaTracker = new MediaTracker(this);
            mediaTracker.addImage(img, 0);
            try {
                mediaTracker.waitForID(0);
            } catch (InterruptedException ex) {
                System.err.println(ex);
        public void paint(Graphics g) {
            g.drawImage(img, 150, 150, this);
        public int print(Graphics g, PageFormat pageFormat,
                int pageIndex) throws PrinterException {
            if(pageIndex>0) {
                return NO_SUCH_PAGE;
            paint(g);
            return Printable.PAGE_EXISTS;
        private Image img=null;
}
