Question

我在java中有一个打印程序，但由于某种原因它总是选择默认打印机（8600），即使我为打印机传递了一个说xps的值，我做错了什么，我怎么能得到它选择所需的打印机

继承我的代码：

 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);
            }
        }

这是控制台：
