Weblogic 10.3 ---- PrintService class is not finding printers

Question

Hi folks,
Am facing an issue in Weblogic 10.3. I have deployed my application which prints the pdf files.
When i am getting print services available in my machine using
*PrintService[] printService =
PrinterJob.lookupPrintServices(); *
its returning printService.length as *0*.
But the same application is working fine in other environments like Oracle Soa Suite 10.1.3.3 and Jdeveloper 10.1.3.3.
Can anybody please suggest on this.
Please find the Sample Code:
import java.awt.print.PrinterJob;
import javax.print.PrintService;
import org.pdfbox.pdmodel.PDDocument;
public class PrintPdf {
public void print(String printerName, String pdfFile) {
PDDocument document = null;
try {
document = PDDocument.load(pdfFile);
PrinterJob printJob = PrinterJob.getPrinterJob();
boolean printerFound = false;
PrintService[] printService = PrinterJob.lookupPrintServices();
System.out.println("printService length: " + printService.length); //* printService.length is returning 0 *
for (int i = 0; i < printService.length; i++) {
System.out.println(i + "==> printService Name: " +
printService.getName());
if (printService[i].getName().indexOf(printerName) != -1) {
printJob.setPrintService(printService[i]);
printerFound = true;
System.out.println("Got Printer");
if (!printerFound) {
System.out.println("Printer Not found");
} else {
printJob.setPageable(document);
printJob.print();
System.out.println("Print Successfull");
} catch (Exception e) {
e.printStackTrace();

Thanks for your help.
When i created a work manager from Deployments -> Configuration -> Workload -> New and the new Work Manager appears in the Application-Scoped Work Managers table. But was not able to see that in Monitering -> Workload Work managers table. Why is that so?
