This program works in Eclipse.

import java.awt.print.PageFormat;

import java.awt.print.PrinterJob;

public class PrinterSetup 
{

    public static void main(String[] args) throws Exception
    {
        PrinterJob pjob = PrinterJob.getPrinterJob();
        PageFormat pf = pjob.defaultPage();
        pjob.setPrintable(null, pf);

        if (pjob.printDialog()) {
          pjob.print();
        }
    }
}

You know how to get list of all printers then you want set a default printer.

ok this code will help you can Pass Name of printer which you want to set as default printer where "MYPRINTER" .replace it with name of printer.

PrinterJob pj = PrinterJob.getPrinterJob();
    PrintService[] printServices = PrintServiceLookup.lookupPrintServices(null, null);
    System.out.println("Number of printers configured: " + printServices.length);
    for (PrintService printer : printServices) {
        System.out.println("Printer: " + printer.getName());
        if (printer.getName().equals("***MYPRINTER***")) {
            try {
                pj.setPrintService(printer);
            } catch (PrinterException ex) {
            }
        }
    }

I made a workaround to set the OS default printer. This one works for windows which basically executes a cmd command that sets the default printer before executing the print code:

Desktop desktop = null
if (Desktop.isDesktopSupported()) {
desktop = Desktop.getDesktop()
    desktop.print(file)
 }

Here's my function:

public static boolean setDefaultPrinter(String printerName) {
    String defaultPrinterSetter = "wmic printer where name='"+ printerName +"' call setdefaultprinter";
    try {
        setDefaultPrinterProcess = Runtime.getRuntime().exec("cmd /c start cmd.exe /C " + defaultPrinterSetter);
        return true;
    } catch (Exception e) {
        e.printStackTrace();
        return false;
    }
}

All you need to do is pass the printer name to this function and it'll make it the default printer.

Here's a function that gets a list of all avaiable printer services:

public static ArrayList<PrintService> availablePrinters() {
    PrintService[] services = PrinterJob.lookupPrintServices();
    ArrayList<PrintService> allServices = new ArrayList<>();

    for (PrintService myService : services) {
        allServices.add(myService);
    }
    return allServices;
}

And I'll assume you'd want to add a list in maybe a combobox or something for user to choose from. It should go something like this

    ArrayList<PrintService> availableServices = availablePrinters();
    System.out.println("All printers list:");
    for (PrintService myService : availableServices) {
        myCombo.getItems().add(myService.getName());
        System.out.println(myService.getName());
    }
