I am printing a Swing component that contains text. The Swing component renders the text just fine on the screen, but, when I print it (to a .tif file), the characters are all smashed together. Why is this?
Run this code to see what I mean:
import javax.swing.*;
import javax.swing.text.MutableAttributeSet;
import javax.swing.text.SimpleAttributeSet;
import javax.swing.text.StyleConstants;
import javax.swing.text.StyledDocument;
import java.awt.*;
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;
public final class PrintingDemo2 implements Printable {
private final JTextPane textPane;
private static final String WORDS = "GOOD MORNING\u00AE AMERICA";
private static final String TEXT = WORDS + '\n' + WORDS + '\n' + WORDS + '\n' + WORDS + '\n' + WORDS + '\n' + WORDS;
public static void main(String[] args) {
new PrintingDemo2();
}
public PrintingDemo2() {
textPane = new JTextPane();
textPane.setText(TEXT);
final StyledDocument document = textPane.getStyledDocument();
String[] fontFamilies = new String[]{"Tahoma", "SimSum", "MS Mincho", "Batang", "Arial", "Times New Roman"};
for (int i = 0; i < fontFamilies.length; i++) {
final MutableAttributeSet attributeSet = new SimpleAttributeSet();
StyleConstants.setFontFamily(attributeSet, fontFamilies[i]);
StyleConstants.setFontSize(attributeSet, 14);
document.setParagraphAttributes(i * 22, 21, attributeSet, true);
}
final AbstractButton printContextButton = new JButton("Print Context");
printContextButton.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
final PrinterJob job = PrinterJob.getPrinterJob();
job.setPrintable(PrintingDemo2.this);
try {
job.print();
} catch (PrinterException ex) {
throw new RuntimeException("Printing Failed.", ex);
}
}
});
final JFrame frame = new JFrame();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
final Container contentPane = frame.getContentPane();
contentPane.setLayout(new BoxLayout(contentPane, BoxLayout.Y_AXIS));
contentPane.add(printContextButton);
contentPane.add(new JScrollPane(textPane));
frame.setSize(400, 200);
SwingUtilities.invokeLater(new Runnable() {
public void run() {
frame.setVisible(true);
}
});
}
public int print(Graphics graphics, PageFormat pageFormat, int pageIndex) throws PrinterException {
if (pageIndex >= 1) return Printable.NO_SUCH_PAGE;
RepaintManager mgr = RepaintManager.currentManager(textPane);
mgr.setDoubleBufferingEnabled(false);
final Graphics2D graphics2D = (Graphics2D) graphics;
graphics2D.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
textPane.paint(graphics);
mgr.setDoubleBufferingEnabled(true);
return Printable.PAGE_EXISTS;
}
}
