  To reproduce simply compile and run the code below on a Linux system (I used
Debian for my tests) with lpr or lprng installed.

I used the below code to test the printing services and got no an array of print
services of 0 length, meaning no printers could be found.

public Print2DPrinterJob() {

/* Construct the print request specification.
* The print data is a Printable object.
* the request additonally specifies a job name, 2 copies, and
* landscape orientation of the media.
*/
PrintRequestAttributeSet aset = new HashPrintRequestAttributeSet();
aset.add(OrientationRequested.LANDSCAPE);
aset.add(new Copies(2));
aset.add(new JobName("My job", null));

/* Create a print job */
PrinterJob pj = PrinterJob.getPrinterJob();
pj.setPrintable(this);
/* locate a print service that can handle the request */
PrintService[] services =
PrinterJob.lookupPrintServices();

if (services.length > 0) {
System.out.println("selected printer " + services[0].getName());
try {
pj.setPrintService(services[0]);
pj.pageDialog(aset);
if(pj.printDialog(aset)) {
pj.print(aset);

System.err.println(pe);

        else
            System.out.println ("No printers available");
}
