The following code does not display the complete print dialog window
but a small corner on Gnone/Enlightenment, with KWM/KDE it works ok

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

public class PrintDialogTest {

        public static void main(String[] args) {
                new PrintDialogTest().run(System.out);
                System.exit(0);
        }

        void run(PrintStream out) {
                PageFormat pf = new PageFormat();
                JFrame frame = new JFrame();
                JPanel p = new JPanel();
                out.println("Toolkit.getPrintJob()");
                p.getToolkit().getPrintJob(frame, "", null);
        }
}
