Printing Sometimes Works, Sometimes Doesn't

Question

I have the most unusual problem, and I'm not expecting any answers. I was wondering, however, if anyone had any ideas about figuring this thing out.
On one computer network (mainly running 1.4.x with Windows 2000) I can print my JComponent absolutely normally with expected results. On another system (NT 1.4.x), the print dialog sometimes comes up/sometimes not. For some, it prints. For others, nothing doing.
I'm mystified and would appreciate any help and ideas. Stuff that breaks some of the time is hard to debug.
Here's the code that handles the printing:
public class PrinterObj {
private static PrinterJob printer = PrinterJob.getPrinterJob();
private static PageFormat page = printer.defaultPage();
public static void pageSetup()
          page = printer.pageDialog(page);
public static void printComponent(JComponent c)
//PrintWrapper is one of our classes
          printer.setPrintable(new PrintWrapper(c), page);
          boolean testbool = printer.printDialog();
          System.out.println("Test the print dialog: " + testbool);
          if(testbool)
          try{
                    printer.print();
          }catch(PrinterException pe){
                    System.out.println(pe.toString());

If anyone wants to know the cause of this problem, here it is:
Java can't print to one of the printers. There are multiple printers on the network, all the same exact model. For whatever reason, one of those printers does not work. It's very weird.
If the bad printer is set as the default printer, the print dialog box won't even show up.
Very weird.
