许多Swing组件支持开箱即用的打印
你可以使用像JTextArea.print
这样简单的东西来开始,例如
import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.EventQueue;
import java.awt.Font;
import java.awt.Graphics2D;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.geom.Rectangle2D;
import java.awt.image.BufferedImage;
import java.awt.print.PageFormat;
import java.awt.print.Paper;
import java.awt.print.Printable;
import java.awt.print.PrinterException;
import java.io.File;
import java.io.IOException;
import java.util.StringJoiner;
import java.util.logging.Level;
import java.util.logging.Logger;
import javax.imageio.ImageIO;
import javax.swing.JButton;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.UIManager;
import javax.swing.UnsupportedLookAndFeelException;
import javax.swing.border.LineBorder;
public class Test {
public static void main(String[] args) {
new Test();
}
public Test() {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
try {
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException | UnsupportedLookAndFeelException ex) {
ex.printStackTrace();
}
JFrame frame = new JFrame("Testing");
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.add(new TestPane());
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
}
});
}
public class TestPane extends JPanel {
private JTextArea ta;
public TestPane() {
setLayout(new BorderLayout());
String[] lines = {
"Idx Met MTU State Name ",
"--- --------- ---------- ------------ --------------------------",
" 1 50 4294967295 connected Loopback Psudo-Interface 1",
" 11 10 1500 connected Local Area Connection ",
" 11 5 1500 disconnected Local Area Connection 3 ",};
StringJoiner joiner = new StringJoiner("\n");
for (String line : lines) {
joiner.add(line);
}
ta = new JTextArea(joiner.toString());
ta.setBorder(new LineBorder(Color.RED));
ta.setFont(new Font("Monospaced", Font.PLAIN, 13));
ta.setWrapStyleWord(true);
add(new JScrollPane(ta));
JButton btn = new JButton("Print");
add(btn, BorderLayout.SOUTH);
btn.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent e) {
try {
ta.print();
} catch (PrinterException ex) {
ex.printStackTrace();
}
}
});
}
}
}
哪个可以输出...
如果您需要打印到非标准页面尺寸,您可能还需要查看How can I print a custom paper size (cheques 8" x 4")?
