How to print the whole JFrame

Question

Hi,
I got this code somewhere from the net.
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.
*  <P>
*  If you are going to be printing many times, it is marginally more
*  efficient to first do the following:
*  <PRE>
*    PrintUtilities printHelper = new PrintUtilities(theComponent);
*  </PRE>
*  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 JFrame componentToBePrinted;
  public static void printComponent(JFrame c) {
    new PrintUtilities(c).print();
  public PrintUtilities(JFrame 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);
  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
  public static void disableDoubleBuffering(Component c) {
    RepaintManager currentManager = RepaintManager.currentManager(c);
    currentManager.setDoubleBufferingEnabled(false);
  /** Re-enables double buffering globally. */
  public static void enableDoubleBuffering(Component c) {
    RepaintManager currentManager = RepaintManager.currentManager(c);
    currentManager.setDoubleBufferingEnabled(true);
}From my main class (where the JFrame resides), the print() method is invoked to print the JFrame. However, when it is printed, it only prints the top left part of the JFrame, not the whole JFrame. Can anyone help please? Thank you very much.

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());
       double xScale = 0.63;
       double yScale = 0.56;
      g2d.scale(xScale, yScale);
      disableDoubleBuffering(componentToBePrinted);     
      componentToBePrinted.paint(g2d);
      enableDoubleBuffering(componentToBePrinted);
      return(PAGE_EXISTS);
  }Hi all,
Alright I managed to scale it to print the whole JFrame. But another problem surfaces. When I select draft quality printing, it doesn't print the whole JFrame. Other printing qualities (standard, high) do print the whole JFrame. I am really puzzled. Anyone has any clue?
And I have an unrelated question to this topic. How do I set a JTextField so that when I click on it the first time, it highlights its content? Have to work around with the mouselistener?
Thank you.
