Printing to a PDF

Question

I have the following class:
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();
       PageFormat pageFormat = new PageFormat();
       if(printJob.pageDialog(printJob.defaultPage()).getOrientation()==pageFormat.LANDSCAPE){
         try{
                 pageFormat.setOrientation(pageFormat.LANDSCAPE);
          catch(java.lang.IllegalStateException ise){
                  System.out.println("Print error...\n"+ise);
      printJob.setPrintable(this,pageFormat);
       if (printJob.printDialog()){
           try{
                printJob.print();
           catch(java.awt.print.PrinterException pe){
                System.out.println("Could not print...\n" + pe);
/*   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;
          Toolkit toolkit = componentToBePrinted.getToolkit();
          /* scaling is added to fit printout of maximized birdseye
          window onto a 8.5 X 11 sheet of paper
          Dimension screenSize = toolkit.getScreenSize();
          //fit screen to printable (landscape) page
          double scaleX = (pageFormat.getImageableWidth()) / (screenSize.getWidth());
          double scaleY = (pageFormat.getImageableHeight())/(screenSize.getHeight());
          if(scaleX>.3){
               double scaleFactor = java.lang.Math.min((double)(screenSize.getWidth())/
               (double)(pageFormat.getImageableWidth()),(double)(screenSize.getHeight())/(double)(pageFormat.getImageableHeight()));
               g2d.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
               g2d.scale(.7/scaleFactor,.95/scaleFactor);
          else{
               double scaleFactor = java.lang.Math.min((double)(screenSize.getWidth())/
               (double)(pageFormat.getImageableWidth()),(double)(screenSize.getHeight())/(double)(pageFormat.getImageableHeight()));
               g2d.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
               g2d.scale(.85/scaleFactor,.95/scaleFactor);
          /** It is important that translation be done before the scaling.
          * Failure to follow this order will result in unusual behavior
          * such as strange cropping
          //g2d.translate(pageFormat.getImageableX(),
          //pageFormat.getImageableY());
          //g2d.scale(scaleX,scaleY);
          // speeds up printing process
          disableDoubleBuffering(componentToBePrinted);
          componentToBePrinted.printAll(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);
}It prints well for the most part. The problem is that I have Adobe Acrobat 6 Professional and I want to
create a pdf using the print class that I have, however it doesn't work. I click the print button in my GUI, and
it calls the PrintUtilities class functions, and I select the printer to be the Adobe PDF Writer, but then I get the following exception message when I click 'ok' to print:
java.lang.IllegalArgumentException: Zero length string passed to TextLayout cons
tructor.

SIr
I am also doing the same to print a component. I need to print a table data. When i send myTable object
PrintUtility.printComponent(myTable).
It just prints as much table data as fits into 1 page. But i want to print whole table data that may be multipage. Please suggest something if can. thanx
