java怎么调用到条码打印机！

 FileOutputStream os = new FileOutputStream("LPT1");

 os.write(yourData);

 os.flush();

PrintService[] services = PrintServiceLookup.lookupPrintServices(null, null);

            PrintService printService = null;

            if (services != null && services.length > 0) {

                String printerName = "zebra";// something like this

                for (PrintService service : services) {

                    if (service.getAttribute(PrinterName.class).getValue().equals(printerName)) {

                        printService = service;

                        break;

                    }

                }

            }

            if (printService == null) {

                //do what you want

            }

            DocPrintJob job = printService.createPrintJob();

            DocFlavor flavor = DocFlavor.INPUT_STREAM.AUTOSENSE;

            Doc doc = new SimpleDoc(new ByteArrayInputStream(yourData), flavor, null);

            try {

                job.print(doc, null);

            } catch (PrintException e) {

                //handle exception

            }

                CommPortIdentifier port = CommPortIdentifier.getPortIdentifier(outputDest);

                ParallelPort parallelPort = (ParallelPort) port.open("some owner", 50);

                OutputStream outputStream = parallelPort.getOutputStream();

                outputStream.write(uccLabelData);

                outputStream.flush();
