1、新建一个窗口类，并实现Printable接口。本文以一条数据为例
2、实现Printable接口的print方法，使用Graphics2D相关绘制出打印的格式图片。
3、使用PrinterJob开启打印进程，导出打印相关的pdf文件
4、导出后的文件如图所示
5、全部代码：import java.awt.BorderLayout;import java.awt.Color;import java.awt.Graphics;import java.awt.Graphics2D;import java.awt.event.ActionEvent;import java.awt.event.ActionListener;import java.awt.print.PageFormat;import java.awt.print.Printable;import java.awt.print.PrinterException;import java.awt.print.PrinterJob;import javax.swing.JButton;import javax.swing.JFrame;import javax.swing.JOptionPane;import javax.swing.JScrollPane;import javax.swing.JTable;public class Frame extends JFrame implements Printable, ActionListener { private Object[][] data = {{"100", "0.8", "0.1", "90"}}; //JTableb表头 private Object[] head = {"单价", "折扣", "税", "调整后价"}; //定义一个存放数据的JTable private JTable table = new JTable(data, head); //打印出一条记录的按钮 private JButton printBtn = new JButton("打印"); private JScrollPane scrollPane = new JScrollPane(table); //设置窗口的信息，添加各种面板按钮，及初始化按钮的监听器。 public Frame() { setSize(800, 600); //设置窗体大小位置 add(printBtn, BorderLayout.NORTH); add(scrollPane, BorderLayout.CENTER); printBtn.addActionListener(this); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setVisible(true); } @Override public void actionPerformed(ActionEvent e) { //获取打印服务对象 PrinterJob job = PrinterJob.getPrinterJob(); job.setPrintable(Frame.this); //添加打印任务 try { job.print(); //执行打印任务 } catch (PrinterException e1) { e1.printStackTrace(); } JOptionPane.showMessageDialog(this, "导出打印pdf文件成功"); } @Override public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException { Graphics2D g = (Graphics2D) graphics; int x = (int)pageFormat.getImageableX(); int y = (int)pageFormat.getImageableY(); switch(pageIndex){ case 0: g.setColor(Color.RED); g.drawString("单价：" + table.getValueAt(0, 0), x + 100, y + 10); g.drawString("折扣：" + table.getValueAt(0, 1), x + 100, y + 30); g.drawString("税率：" + table.getValueAt(0, 2), x + 100, y + 50); g.drawString("单价：" + table.getValueAt(0, 3), x + 100, y + 70); return PAGE_EXISTS; default: return NO_SUCH_PAGE; } } public static void main(String[] args) { new Frame(); }}
