silentPrint method

[Victor José Bento <vj...@gmail.com>]

Hi. I'm trying to create an applet to use the method silentPrint, the
applet works when I run it on NetBeans, but when I try to load it on my
webpage (yes I signed all jar files) I can just print my PDF files to a
printer that generate tiff files (Microsoft Office Document Image Writer), I
can't use the Samsung SCX-4x21 Series, that works when I run the applet on
NetBeans. Using silentPrint() or print() from my webpage I get the following
exception, someone can help me?

Now my method:

public static String Print(final String printerName, final String
urlDocument)
    {
        String retornoFinal = "";
        retornoFinal = (String)AccessController.doPrivileged(new
PrivilegedAction<String>()
        {
            public String run()
            {
                String retorno = "";
                boolean erro = true;
                PDDocument impressao = null;
                try
                {
                    PrintService impressoras[] =
PrintServiceLookup.lookupPrintServices(null, null);
                    PrinterJob printerJob = PrinterJob.getPrinterJob();
                    impressao = PDDocument.load(new
URL(urlDocument).openStream());
                    for(int i = 0; i < impressoras.length; i++)
                    {
                        if
(impressoras[i].getName().equalsIgnoreCase(printerName.trim()))
                        {
                            printerJob.setPrintService(impressoras[i]);
                            erro = false;
                            break;
                        }
                    }
                    if (erro)
                    {
                        retorno += "Não foi possível encontrar a impressora
" + printerName.trim();
                    }
                    else
                    {
                        impressao.silentPrint(printerJob);
                    }
                }
                catch (Exception ex)
                {
                    ex.printStackTrace();
                }
                finally
                {
                    try {
                        impressao.close();
                    } catch (IOException ex) {

Logger.getLogger(DMApplet.class.getName()).log(Level.SEVERE, null, ex);
                    }
                }
                return retorno;
            }
        });
        return retornoFinal;
    }

Thanks!
