PrinterJob.lookupPrintServices () возвращает пустой массив в системе Ubuntu 16

Question

Мой тестовый код приведен ниже

final static Logger LOGGER = Logger.getLogger(App.class);
    private static String location = "";
    public static PrintService choosePrinter(String printerName) {
        PrintService[] services = PrinterJob.lookupPrintServices(); // list of printers
        System.out.println("services : " +services);
        LOGGER.info("services : " + services);
        PrintService printService = null;
        //int count = service.length;

        /*
        for (int i = 0; i < count; i++) {
            String availablePrinterName = service.getName();
            System.out.println(availablePrinterName);
            if (service[i].getName().equalsIgnoreCase(printerName)) {
                printService = service[i];
                i = count;
            }
        }*/

        PrintService ps = PrintServiceLookup.lookupDefaultPrintService();
        System.out.println("services : " +ps.getName());
        LOGGER.info("services : " + ps.getName());


        if(services != null) {
            System.out.println("availablePrinter count: " +services.length);
            LOGGER.info("availablePrinter count: " + services.length);
        }


        for(PrintService service : services) {

Этот код печатает документ без проблем. моя локальная машина windows и машина Ubuntu 17. Когда я использовал тот же код для печати, он не работает в Ubuntu 16. Я не уверен, если его проблема конфигурации. Мой журнал как указано ниже. Есть идеи?
