I installed a cups server on Ubuntu 16, after installed a POS printer, after tested test page and lpr command line command and it works ok; in java using PrintJob, java find the printer, but no printer anything....

some ideas to fix this problem??

I had the same problem some time ago, i did this, maybe could help you. Let me know.

public static boolean imprimirDocto(String documentPath, String printerName) {

        File f = new File(documentPath);

        try {

            PDDocument doc = PDDocument.load(f);



            PrinterJob pj = PrinterJob.getPrinterJob();



            PrintService ps = PrintServiceLookup.lookupPrintServices(null, null);

            PrintService printService = null;

            if (ps.length > 0) {

                //This searchs for all the printers, and looks for the 'printerName'

                for (int i = 0; i < ps.length; i++) {

                    System.out.println("Printer name: " + ps[i]);

                    if (ps[i].getName().toLowerCase().contains(printerName.toLowerCase())

                            || ps[i].getName().contains(printerName)) {



                        printService = ps[i];



                        System.out.println("Setting the printer...");

                        pj.setPrintService(printService);

                        i = ps.length;

                    }

                }



                pj.setPageable(new PDFPageable(doc));

                pj.print();



                return true;



            } else {

                return false;

            }



        } catch (Exception e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

            return false;

        }

    }
