Please help in prining JPanel

Hey friends,
I want to print a JPanel along with its component for which i have my PrintUtilities class as I attached it.

Here the problem is that whenever i want to print the jPanel i have to passed it through parameter of printComponent(Component) method and it shows me the print dialog.

What i actually want is to show the printDialog only once in running application for printing setup and after that it directly prints the component whenever i call the printComponent() method.

Please suggest me what i have to change in my code???

Please help me...

Here is the same code what i have attached before:

package Classes;

import java.awt.*;
import javax.swing.*;
import java.awt.print.*;

public class PrintUtilities implements Printable {
private Component componentToBePrinted;


public static void printComponent(Component c) {
new PrintUtilities(c).print();
}

public PrintUtilities(Component componentToBePrinted) {
this.componentToBePrinted = componentToBePrinted;
}

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);
}
}

@Override
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);
}
}

public static void disableDoubleBuffering(Component c) {
RepaintManager currentManager = RepaintManager.currentManager(c);
currentManager.setDoubleBufferingEnabled(false);
}

public static void enableDoubleBuffering(Component c) {
RepaintManager currentManager = RepaintManager.currentManager(c);
currentManager.setDoubleBufferingEnabled(true);
}
}
