PrintDialog tabs

Question

Hello all,
I was exploring the Java Print tutorial trail. I began with HelloWorldPrinter.java, the print dialog displays 3 tabs: General, Page Setup, Appearance. On the General tab, the button with label "Properties" is disabled. On the Apperance tab, the radio button group titled "Color Appearance" has 2 radio buttons: Monochrome (disabled), Color (enabled, this is weird because my printer is not a color printer); another radio button group tittled "Quality" has 3 radio buttons: Draft, Normal, High (all disalbed).
Why are those buttons diabled, how can one enable them?
Thank you for your help!
My JDK version is 1.5.0_06 running on RedHat linux. Below is the code listing of the HelloWordPrinter.java:
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.awt.print.*;
public class HelloWorldPrinter implements Printable, ActionListener {
    public int print(Graphics g, PageFormat pf, int page) throws
                                                        PrinterException {
        if (page > 0) { /* We have only one page, and 'page' is zero-based */
            return NO_SUCH_PAGE;
        /* User (0,0) is typically outside the imageable area, so we must
         * translate by the X and Y values in the PageFormat to avoid clipping
        Graphics2D g2d = (Graphics2D)g;
        g2d.translate(pf.getImageableX(), pf.getImageableY());
        /* Now we perform our rendering */
        g.drawString("Hello world!", 100, 100);
        /* tell the caller that this page is part of the printed document */
        return PAGE_EXISTS;
    public void actionPerformed(ActionEvent e) {
         PrinterJob job = PrinterJob.getPrinterJob();
         job.setPrintable(this);
         boolean ok = job.printDialog();
         if (ok) {
             try {
                  job.print();
             } catch (PrinterException ex) {
              /* The job did not successfully complete */
    public static void main(String args[]) {
        UIManager.put("swing.boldMetal", Boolean.FALSE);
        JFrame f = new JFrame("Hello World Printer");
        f.addWindowListener(new WindowAdapter() {
           public void windowClosing(WindowEvent e) {System.exit(0);}
        JButton printButton = new JButton("Print Hello World");
        printButton.addActionListener(new HelloWorldPrinter());
        f.add("Center", printButton);
        f.pack();
        f.setVisible(true);
}

Answer 1

those buttons you've mentioned will be enabled/disabled depending on the selected Print Service (in the General Tab). Try changing you selection and see how they behave.
