How to use Java to print on a network printer?

In my case there was an authentication error, I could not find shared printer because i searched them with LocalUser account, using another account or changing printer grants I could find it.

Java AWT Printing will not find a printer via a path if it is not registered to the Windows / Active Directory user that is running the printing application. You must register the printer path through Windows "Devices and Printers" as a printer for that user for it to be visible. Then, as that user, you must run lookupPrintServices to see the list of printers available and retrieve the proper PrintService by the exact name String listed.

/**
 * Retrieve the specified Print Service; will return null if not found.
 * @return
 */
public static PrintService findPrintService(String printerName) {

    PrintService service = null;
    
    // Get array of all print services - sort order NOT GUARANTEED!
    PrintService[] services = PrinterJob.lookupPrintServices();
    
    // Retrieve specified print service from the array
    for (int index = 0; service == null && index < services.length; index++) {
        
        if (services[index].getName().equalsIgnoreCase(printerName)) {

            service = services[index];
        }
    }

    // Return the print service
    return service;
}

/**
 * Retrieve a PrinterJob instance set with the PrinterService using the printerName.
 * 
 * @return
 * @throws Exception IllegalStateException if expected printer is not found.
 */
public static PrinterJob findPrinterJob(String printerName) throws Exception {

    // Retrieve the Printer Service
    PrintService printService = PrintUtility.findPrintService(printerName);

    // Validate the Printer Service
    if (printService == null) {

        throw new IllegalStateException("Unrecognized Printer Service \"" + printerName + '"');
    }
    
    // Obtain a Printer Job instance.
    PrinterJob printerJob = PrinterJob.getPrinterJob();
    
    // Set the Print Service.
    printerJob.setPrintService(printService);

    // Return Print Job
    return printerJob;
}

/**
 * Printer list does not necessarily refresh if you change the list of 
 * printers within the O/S; you can run this to refresh if necessary.
 */
public static void refreshSystemPrinterList() {

    Class[] classes = PrintServiceLookup.class.getDeclaredClasses();

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

        if ("javax.print.PrintServiceLookup$Services".equals(classes[i].getName())) {

            sun.awt.AppContext.getAppContext().remove(classes[i]);
            break;
        }
    }
}
