Question

我正在尝试创建一个程序，用于打印jTextArea中的内容我的问题是，当printDialog弹出并按下OK时，打印机不会打印或者当我将属性更改为纸张来源到 Cont.Feed-无中断时，它会给出一个空白页面我试图在热敏收据打印机上打印

这是我的代码

public int print(Graphics g, PageFormat pf, int page) throws
                                                    PrinterException {

    if (page > 0) {
        return NO_SUCH_PAGE;
    }

    Graphics2D g2d = (Graphics2D)g;
    g2d.translate(pf.getImageableX(), pf.getImageableY()-55);

    frameToPrint.print(g);

    return PAGE_EXISTS;
}

public void actionPerformed(ActionEvent e) {
     PrinterJob job = PrinterJob.getPrinterJob();
     job.setPrintable(this);
     boolean ok = job.printDialog();
     if (ok) {
         try {
              job.print();
         } catch (PrinterException ex) {

         }
     }
}

public PrintUIWindow(JFrame f) {
    frameToPrint = f;
}

public static void main(String args[]) {
    UIManager.put("swing.boldMetal", Boolean.FALSE);
    JFrame f = new JFrame("Print UI Example");
    f.addWindowListener(new WindowAdapter() {
       public void windowClosing(WindowEvent e) {System.exit(0);}
    });

    JLabel label1=new JLabel("Selling Bill",JLabel.CENTER);
    JLabel label2=new JLabel("Customer Name :Mahmoud Saleh       ",JLabel.LEFT);
    JLabel label3=new JLabel("Buying Date :29/8/2008             ",JLabel.LEFT);
    JLabel label4=new JLabel("Book Buyed :Java Printing          ",JLabel.LEFT);
    JLabel label5=new JLabel("Number : 6 Copies                  ",JLabel.LEFT);
    JLabel label6=new JLabel("Total Price :600 $                 ",JLabel.LEFT);

    label1.setFont(new Font("Courier New", Font.BOLD, 13));
    label2.setFont(new Font("Courier New", Font.BOLD, 13));
    label3.setFont(new Font("Courier New", Font.BOLD, 13));
    label4.setFont(new Font("Courier New", Font.BOLD, 13));
    label5.setFont(new Font("Courier New", Font.BOLD, 13));
    label6.setFont(new Font("Courier New", Font.BOLD, 13));

    JButton printButton = new JButton("Print This Window");
    printButton.addActionListener(new PrintUIWindow(f));
    JPanel panel=new JPanel();
    panel.setLayout(new GridLayout(6,1));
    panel.add(label1);
    panel.add(label2);
    panel.add(label3);
    panel.add(label4);
    panel.add(label5);
    panel.add(label6);
    f.setSize(300,300);
    f.setLocationRelativeTo(null);
    f.add(panel,BorderLayout.CENTER);
    f.add(printButton,BorderLayout.SOUTH);
    panel.setBackground(Color.WHITE);
    f.setResizable(false);
    f.setVisible(true);
}
