Print dialog not displaying when trying to print PDF document

Question

Hello All,
I am using below code to print a pdf file. And the same code working fine when i am using with simple java class. and if i am using the same code with my jsf backing bean action method it was not working.
Code here:
Document document = new Document();
FileOutputStream combinedOutput = new FileOutputStream(bulkBarcodes);
PdfWriter.getInstance(document, combinedOutput);
document.open();
String barCodeNum = filetrakcode.getBarCodeID().toString();
Barcode bc = new Barcode(barCodeNum, DEFAULT_CONFIG_FILE);
document.add(new Paragraph("\n"));
document.add(new Paragraph("\n"));
Image image = Image.getInstance(bc.generateBarcodeBytes(bc.getBarcode()));
document.add(image);
combinedOutput.flush();
document.close();
combinedOutput.close();
File f = new File(bulkBarcodes.getAbsolutePath());
FileInputStream fis = new FileInputStream(f);
FileChannel fc = fis.getChannel();
ByteBuffer bb = fc.map(FileChannel.MapMode.READ_ONLY, 0, fc.size());
PDFFile pdfFile = new PDFFile(bb); // Create PDF Print Page
PDFPrintPage pages = new PDFPrintPage(pdfFile);
PrinterJob printJob = PrinterJob.getPrinterJob();
PageFormat pf = PrinterJob.getPrinterJob().defaultPage();
printJob.setJobName(f.getName());
Book book = new Book();
book.append(pages, pf, pdfFile.getNumPages());
printJob.setPageable(book);
//Send print job to default printer
if(printJob.printDialog())
printJob.print();
When i am calling my action method (method contains above code) it was creating pdf file and writing the data init success fully but when i have not used "if(printJob.printDialog())" it was printing document directely successfully but when i am calling "if(printJob.printDialog())" it was not opening print dialog box and it was showing me like process is going on and it was not proceeding further
what's the problem
Please help me.
Thanks In advance,
Indira.

Hi Kavi,
just have a look into the driver-program. I'm pretty sure someone has programmed a loop.
IF it is a NAST-driver program, check if your specific user has a printer SU03. That sounds a lot like this mistake
