Printing in Mac OS X

Question

Hello all,
I created a printable class that works in Windows and Linux, but for some reason will not work on Mac OS X. It either prints a blank page or throws a nasty exception:
Exception in thread "Thread-0" java.lang.NullPointerException

I am using Java 1.4.2. Any ideas?
Here is my code:
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();
       printJob.setPrintable(this, 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);
  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();
          /** 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(.45,.45);
          //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);
}Thanks

Trouble printint to a Dell Laser MFP 1815dn.
Check if the Dell driver is PPC. If it is, and if you installed the first version of Apple's latest Security Update, then that's probably where the issue is, because it broke Rosetta, the software which runs PPC code under SL. Re-install the Sec Update (the problem is fixed in v1.1, which replaced the goofy version on Apple's servers) through Software Update or by downloading it again, then re-install the Dell driver, and try again.
Apple stuff is great, except for their casual disregard of their customers who want to use any product that is not Apple
I'm sorry, but that's non-sense. I'm no fan of Apple, but they're no better and no worse than any large corporation of this type. Mostly, they do things which make business sense as they see it -- which is exactly what you'd want, if you had serious money invested in Apple shares -- wouldn't you?
In this instance, it was up to Dell to release an Intel Mac driver for this printer/scanner, which is, what, 5 or 6 years old? If they didn't, it was probably because they decided it didn't make business sense for them to spend money on developing and testing one. Keep in mind that Dell and Apple and Microsoft and all the rest are in business to make money, not to support every single customer for ever and ever and a day.
