A DESCRIPTION OF THE PROBLEM :
The following Test.java program gives a dialog window in XPx64, but not in Ubuntu Linux.
//################### Test printDialog show only ############
import java.awt.print.PrinterJob;
public class Test {
  Test test;
  public static void main(String[]args) {
    Test test=new Test(); test.test=test; test.main2(); //escape static
  }
  protected void main2() { //escapes static
    PrinterJob prJ;
    prJ=PrinterJob.getPrinterJob();
    System.out.println("------------------LOOK FOR & CLICK PRINT DIALOG");
    if(prJ.printDialog()) { //Doesn't show window in Linux, but does in Windows
    } //pause("after printDialog");
  }
}
Running gives the following output in Ubuntu Linux.
