This program works in Eclipse.

这个程序在 Eclipse 中工作。

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.

您知道如何获取所有打印机的列表，然后您想设置默认打印机。

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.

好的，此代码将帮助您传递要设置为默认打印机的打印机名称，其中“MYPRINTER”。将其替换为打印机名称。

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:

我做了一个解决方法来设置操作系统默认打印机。这个适用于 Windows，它基本上执行一个 cmd 命令，在执行打印代码之前设置默认打印机：

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

Here's my function:

这是我的功能：

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.

您需要做的就是将打印机名称传递给此函数，它将使其成为默认打印机。

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

这是一个获取所有可用打印机服务列表的函数：

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

我假设您想在组合框或其他内容中添加一个列表供用户选择。它应该是这样的

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