始终选择默认打印机，而不是指定的JAVA打印机

我有一个java打印程序，但出于某种原因，它总是选择默认打印机（8600），即使我传递了一个值（比如xps for printer），我做错了什么，如何让它选择所需的打印机

这是我的密码：

 PrintService[] printServices = PrintServiceLookup.lookupPrintServices(null, null);
        System.out.println("Number of print services: " + printServices.length); //tells me how many print services are isntalled on the server.

        for (PrintService printer2 : printServices) {
            System.out.println("Printer: " + printer2.getName()); //prints out the names of all printers on the server, testing purposes 
        } 


        PrintUtility.findPrintService(printer); // selects only the 8600 printer // EDIT now selects any printer with the name provided


        PrintService[] services =
                PrintServiceLookup.lookupPrintServices(psInFormat, null);
        //System.out.println("Printers avialiable are " + services);
        System.out.println("Printer Selected " + services[Printerinx]);

        //PrintService defaultService = PrintServiceLookup.lookupDefaultPrintService();

        DocFlavor[] docFalvor = services[Printerinx].getSupportedDocFlavors();
        for (int i = 0; i < docFalvor.length; i++) {
            System.out.println(docFalvor[i].getMimeType());
        }
        if (services.length > 0) {
            DocPrintJob job = services[Printerinx].createPrintJob();
            try {
                job.print(myDoc, aset);
                System.out.print("Printing Doc");
            } catch (PrintException pe) {
                System.out.print(pe);
            }
        }

感谢

确定已解决，printerinx，我已选择可使用的打印机，第一台为0等，我已将其设置为printinx=“3”，因此它总是选择第四台打印机，这台打印机已被删除，每个打印机都已获得正确的printinx，现在它已正常工作
