Problem with printer in java

I have a problem, what happens is I want to send to print a file at a printer, for which I get the IP address of the printers I have networked and choose the first, here is the code for this: 

PrintService[] service = PrinterJob.lookupPrintServices();// list of ip address 

PrinterJob printJob = PrinterJob.getPrinterJob();

printJob.setPrintService(service[0]);//I get the first address

But now I want to assign the string that contains the IP address:\\10.100.20.26\My printer of the printer that I want, and not the network that I have, and it is there that do not know how , someone please help me, I've searched for the solution, but I have not had good results.

 public void printFile(File file, String printerIp) throws PrintException, IOException {

        Socket socket = new Socket(printerIp, 9100);

        FileInputStream fileInputStream = new FileInputStream(file);
        byte [] mybytearray  = new byte [(int)file.length()];

        fileInputStream.read(mybytearray,0,mybytearray.length);

        OutputStream outputStream = socket.getOutputStream();

        outputStream.write(mybytearray,0,mybytearray.length);

             //Curious thing is that we have to wait some time to make more prints.
        try {
            Thread.sleep(500);
        } catch (InterruptedException e) {

        }

        outputStream.flush();
        outputStream.close();
        socket.close();
        fileInputStream.close();
    }

    //void main
      File f = new File("C:\\Users\\SHINWAR\\Desktop\\link.txt");
    try {
        printFile(f, "192.168.1.100"); //f : file to print , ip printer
    } catch (Exception e) {
        System.out.println(e + "--file");
    }

print from ip and send file .txt

I am guessing that the PrintService has some property that give you its path. So go over the array of PrintServices to find one that matches the path you have and use it:

PrintService[] services = PrinterJob.lookupPrintServices();// list of ip address
String myPrinter = "10.100.20.26\My printer";
PrintService serviceToUse = null;

for (PrintService service: services) {
    if (service.getPath().equals(myPrinter)) {
        serviceToUse = service;
        break;
    }
}

if (serviceToUse != null) {
    PrinterJob printJob = PrinterJob.getPrinterJob();

    printJob.setPrintService(serviceToUse);
}
