Question

基本上我正在创建一个java独立应用程序，其中学生首先提供他的全部细节。

单击打印按钮时，我想以指定的格式打印学生提供的一些数据

像：

//logo goes here


                         regn no:
                         regn date:
name:
phnno:
mail:

怎么做？

Answer 1

如果您想使用任何格式而不是纯文本进行Java打印，则需要使用javax.print。它与2D图形非常相似。

查看http://docs.oracle.com/javase/tutorial/2d/printing/的官方教程，了解如何操作。

来自http://docs.oracle.com/javase/tutorial/displayCode.html?code=http://docs.oracle.com/javase/tutorial/2d/printing/examples/HelloWorldPrinter.java（未经测试）：

import java.awt.*;
import java.awt.event.*;
import javax.swing.*;
import java.awt.print.*;

public class HelloWorldPrinter implements Printable, ActionListener {


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

        if (page > 0) { /* We have only one page, and 'page' is zero-based */
            return NO_SUCH_PAGE;
        }

        /* User (0,0) is typically outside the imageable area, so we must
         * translate by the X and Y values in the PageFormat to avoid clipping
         */
        Graphics2D g2d = (Graphics2D)g;
        g2d.translate(pf.getImageableX(), pf.getImageableY());

        /* Now we perform our rendering */
        g.drawString("Hello world!", 100, 100);

        /* tell the caller that this page is part of the printed document */
        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) {
              /* The job did not successfully complete */
             }
         }
    }

    public static void main(String args[]) {

        UIManager.put("swing.boldMetal", Boolean.FALSE);
        JFrame f = new JFrame("Hello World Printer");
        f.addWindowListener(new WindowAdapter() {
           public void windowClosing(WindowEvent e) {System.exit(0);}
        });
        JButton printButton = new JButton("Print Hello World");
        printButton.addActionListener(new HelloWorldPrinter());
        f.add("Center", printButton);
        f.pack();
        f.setVisible(true);
    }
}
