PDDocument getPrintable endless loop

[Gyenes István]

Hi All!

I'm new in BDFBox.
I try to print one page to specified tray, but it is make an endless 
printing loop. I do something wrong or it is a bug in the library?
My source code is:
 PDDocument pdf = 
PDDocument.load("c:\\Java\\nb74_projects\\lpu\\AISB08.pdf");
        PrintService[] ps = PrinterJob.lookupPrintServices();
        for (int x=1; x<ps.length; x++) {
            System.out.println(ps[x].getName());
            if (ps[x].getName().compareTo("Canon Generic PCL6 
Driver")==0) {
                PrinterJob pj = PrinterJob.getPrinterJob();
                pj.setPrintService(ps[x]);
                PrintRequestAttributeSet pset = new 
HashPrintRequestAttributeSet();
                pset.add(MediaTray.TOP);
                pj.setPrintable(pdf.getPrintable(0));
                pj.print(pset);
            }
        }
Big thanks for any help!
