You should use PrintServiceLookup
你应该使用 PrintServiceLookup
import javax.print.PrintServiceLookup;
PrintService service = PrintServiceLookup.lookupDefaultPrintService();
Acc. to Javadocs:
累积 到 Javadocs：
lookupDefaultPrintServiceLocates the default print service for this environment. This may return null. If multiple lookup services each specify a default, the chosen service is not precisely defined, but a platform native service, rather than an installed service, is usually returned as the default. If there is no clearly identifiable platform native default print service, the default is the first to be located in an implementation-dependent manner.
lookupDefaultPrintService定位此环境的默认打印服务。这可能会返回 null。如果多个查找服务各自指定一个默认值，则不会精确定义所选服务，但通常会返回平台本机服务而不是已安装的服务作为默认值。如果没有明确可识别的平台本机默认打印服务，则以依赖于实现的方式首先定位默认打印服务。

You could use PrintServiceLookup.lookupDefaultPrintService
您可以使用PrintServiceLookup.lookupDefaultPrintService
PrintService service =
PrintServiceLookup.lookupDefaultPrintService();
if (service != null) {
String printServiceName = service.getName();
System.out.println("Print Service Name is " + printServiceName);
} else {
System.out.println("No default print service found");
}
