如何在打印机作业java中完成后停止打印

Question

我的打印机作业出现问题。。我已经设置好了脚本和纸张大小，但打印机总是在打印完成后滚动。。我使用epson LX-300+II在我的epson LX-300、LX-310和LX-800中，打印正常运行，完成打印时打印机自动停止，但在我的epson LX-300+II中，打印机总是在完成打印后滚动。我不知道为什么，我用同样的脚本打印。。这是我设置自定义纸张大小的脚本：

public void setPrinter(String textParam, String spesialWords, int gotoX2) {
    try {
        String destination = "";
        boolean printToDoc = true;
        PrinterJob pj = PrinterJob.getPrinterJob();
        //boolean printDialog = pj.printDialog();
        System.out.println("--------------------");
        //PageFormat pf = pj.getPageFormat(null);
        PageFormat pf = pj.defaultPage();
        Paper paper = pf.getPaper();
        double cm = 72.0 / 2.54;
        if (!destination.equalsIgnoreCase("document.pdf")) {
            if (destination.equalsIgnoreCase("printer")) {
                paper.setSize(26 * cm, 7 * cm);
            }
        }
                paper.setSize(23 * cm, 7 * cm);
        double getHeight = 7 * cm;
        double getWidth = 23 * cm;
        double margin = 0.0; // half inch
        paper.setImageableArea(margin, margin, paper.getWidth(), paper.getHeight());
        pf.setPaper(paper);
        System.out.println("==========================================");
        System.out.println("paper height : "+getHeight);
        System.out.println("paper width : "+getWidth);
        PrintRequestAttributeSet attr_set = new HashPrintRequestAttributeSet();
        if (destination.equalsIgnoreCase("document.pdf")) {
            PrintService defaultPrintService = PrintServiceLookup.lookupDefaultPrintService();
            DocPrintJob printerJob = defaultPrintService.createPrintJob();
            File pdfFile = new File(destination);
            SimpleDoc simpleDoc = new SimpleDoc(pdfFile.toURL(), DocFlavor.URL.AUTOSENSE, null);
            try {
                printerJob.print(simpleDoc, null);
            } catch (PrintException ex) {
                Logger.getLogger(Printing2.class.getName()).log(Level.SEVERE, null, ex);
            }
        } else if (destination.equalsIgnoreCase("document.ps")) {
            try {
                if (textParam.toLowerCase().contains("post")) {
                    destination = "post_"+destination;
                } else if (textParam.toLowerCase().contains("non")) {
                    destination = "non_"+destination;
                } else if (textParam.toLowerCase().contains("token")) {
                    destination = "pre_"+destination;
                }
                attr_set.add(new Destination(new java.net.URI("file:" + destination)));
            } catch (URISyntaxException ex) {
                Logger.getLogger(Printing2.class.getName()).log(Level.SEVERE, null, ex);
            }
        }
        PrinterResolution pr = new PrinterResolution(120, 144, PrinterResolution.DPI);
        attr_set.add(pr);
        pj.setPrintable(new MyPrintable(textParam, spesialWords, gotoX2), pf);
        if (!destination.equalsIgnoreCase("document.pdf")) {
            try {
                //System.out.println("ini print");
                if (destination.equalsIgnoreCase("xps")) {
                    pj.print();
                } else {
                    pj.print(attr_set);
                }
            } catch (PrinterException e) {
                System.out.println(e);
                javax.swing.JOptionPane.showMessageDialog(rootPane, "Gagal mencetak struk, Silahkan lihat pengaturan printer anda");
            }
        }
    } catch (IOException ex) {
        //System.out.println("testing cuuy");
        Logger.getLogger(Printing2.class.getName()).log(Level.SEVERE, null, ex);
    }
}

我用以下方法解决问题：将lx-300+II的驱动程序打印机更改为lx-800我不知道为什么。但它运行得很好
