Hi there, i have following problem: I got zk web application with printing function, but have problem with printing. After i click on "print" button document is sent to printer on server but i want to send it to my local printer.

this is my printing service source code:

public class PrintingServiceImpl implements PrintingService {

public void printEtiket(String harnessType, String version, String jobOrder, String date, String matrixData){
    BufferedReader br = null;
    String stringToPrint =null;

    try {
        String path=PrintingServiceImpl.class.getClassLoader().getResource("PrintingPattern.zpl").toString();
        path = path.replaceAll("file:/", "");
        Scanner in = new Scanner(new FileReader(path));
        StringBuilder sb = new StringBuilder();
        String line=null;
        while (in.hasNextLine()){
            line=in.nextLine();
            if (line.contains("<@harnessType>")){line=line.replace("<@harnessType>", harnessType);}
            if (line.contains("<@version>")){line=line.replace("<@version>", version);}
            if (line.contains("<@jobOrder>")){line=line.replace("<@jobOrder>", jobOrder);}
            if (line.contains("<@date>")){line=line.replace("<@date>", date);}
            if (line.contains("<@matrixData>")){line=line.replace("<@matrixData>", matrixData);}
            sb.append(line);
            sb.append("\n");
        }stringToPrint = sb.toString();
    } catch (FileNotFoundException e1) {
        e1.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
    }

    try {

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

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

            PrintServiceAttribute attr = services[i].getAttribute(PrinterName.class);
            sPrinterName = ((PrinterName) attr).getValue();

            if (sPrinterName.toLowerCase().indexOf("gx420") >= 0) {
                psZebra = services[i];
                break;
            }
        }
        if (psZebra == null) {
            System.out.println("Zebra printer is not found.");
            //return;
        }
        DocPrintJob job = psZebra.createPrintJob();
        byte[] by = stringToPrint.getBytes();
        DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE;
        Doc doc = new SimpleDoc(by, flavor, null);
        job.print(doc, null);

    } catch (PrintException e1) {
        e1.printStackTrace();
    }
}
public void printJobOrder(int id, int orderNumber, String aliasName){

    BufferedReader br = null;
    String stringToPrint =null;
    try {
        String path=PrintingServiceImpl.class.getClassLoader().getResource("PrintingPattern.zpl").toString();
        path = path.replaceAll("file:/", "/");
        System.out.printf("++++++++++++++++   "+path);
        Scanner in = new Scanner(new FileReader(path));
        StringBuilder sb = new StringBuilder();
        String line=null;
        while (in.hasNextLine()){
            line=in.nextLine();

            if (line.contains("<@jobOrderId>")){line=line.replace("<@jobOrderId>", ""+id);}
            if (line.contains("<@orderNumber>")){line=line.replace("<@orderNumber>", ""+orderNumber);}
            if (line.contains("<@aliasName>")){line=line.replace("<@aliasName>", aliasName);}
            sb.append(line);
            sb.append("\n");
        }stringToPrint = sb.toString();
    } catch (FileNotFoundException e1) {
        e1.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
    }

    try {

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

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

            PrintServiceAttribute attr = services[i].getAttribute(PrinterName.class);
            sPrinterName = ((PrinterName) attr).getValue();

            if (sPrinterName.toLowerCase().indexOf("gx420") >= 0) {
                psZebra = services[i];
                break;
            }
        }
        if (psZebra == null) {
            System.out.println("Zebra printer is not found.");
            //return;
        }
        DocPrintJob job = psZebra.createPrintJob();
        byte[] by = stringToPrint.getBytes();
        DocFlavor flavor = DocFlavor.BYTE_ARRAY.AUTOSENSE;
        Doc doc = new SimpleDoc(by, flavor, null);
        job.print(doc, null);

    } catch (PrintException e1) {
        e1.printStackTrace();
    }
}

}

Any ideas how to send document to my local printer? Thx for answers.
