发现默认打印服务

要发现默认打印服务，我们可以使用 PrintServiceLookup 类。让我们看看如何::

import javax.print.PrintService;
import javax.print.PrintServiceLookup;

public class DiscoveringDefaultPrintService {

    public static void main(String[] args) {
        discoverDefaultPrintService();
    }

    public static void discoverDefaultPrintService() {
        PrintService defaultPrintService = PrintServiceLookup.lookupDefaultPrintService();
        System.out.println("Default print service name: " + defaultPrintService.getName());
    }

}
