I have a JTextArea in which a file contents are displayed.I am using the PrintUtilities.java code to print the JTextArea. But this prints only the contents visble on the screen and not the whole document . How do I solve this problem.This also happens for the graphics displayed in a JPanel. The PrintUtilities code is as follows public class PrintUtilities implements Printable { private Component componentToBePrinted; public static void printComponent(Component c) { new PrintUtilities(c).print(); } public PrintUtilities(Component componentToBePrinted) { this.componentToBePrinted = componentToBePrinted; } public void print() { PrinterJob print   More>>

I have a JTextArea in which a file contents are displayed.I am using the PrintUtilities.java code to print the JTextArea. But this prints only the contents visble on the screen and not the whole document . How do I solve this problem.This also happens for the graphics displayed in a JPanel.

The PrintUtilities code is as follows

			
public class PrintUtilities implements Printable {
private Component componentToBePrinted;

public static void printComponent(Component c) {
new PrintUtilities(c).print();
}

public PrintUtilities(Component componentToBePrinted) {
this.componentToBePrinted = componentToBePrinted;
}

public void print() {
PrinterJob printJob = PrinterJob.getPrinterJob();
printJob.setPrintable(this);
if (printJob.printDialog())
try {
printJob.print();
} catch(PrinterException pe) {
System.out.println("Error printing: " + pe);
}
}

public int print(Graphics g, PageFormat pageFormat, int pageIndex) {
if (pageIndex > 0) {
return(NO_SUCH_PAGE);
} else {
Graphics2D g2d = (Graphics2D)g;
g2d.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
disableDoubleBuffering(componentToBePrinted);
componentToBePrinted.paint(g2d);
enableDoubleBuffering(componentToBePrinted);
return(PAGE_EXISTS);
}
}
public static void disableDoubleBuffering(Component c) {
RepaintManager currentManager = RepaintManager.currentManager(c);
currentManager.setDoubleBufferingEnabled(false);
}

/** Re-enables double buffering globally. */

public static void enableDoubleBuffering(Component c) {
RepaintManager currentManager = RepaintManager.currentManager(c);
currentManager.setDoubleBufferingEnabled(true);
}

The print_actionPerformed has

PrintUtilities.printComponent(JTextArea1);
