Try following java file to print java component.
Just call printComponent(Component c) method to print component.
import java.awt.*;
import java.awt.print.*;
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() {
//Prints A4 size page
PrinterJob printJob = PrinterJob.getPrinterJob();
if (printJob.printDialog())
try {
printJob.print();
} catch(PrinterException pe) {
System.out.println("Error printing: " + pe);
}
}
public int print(Graphics g, PageFormat pageFormat, int pageIndex) {
Graphics2D g2d = (Graphics2D)g;
g2d.translate(pageFormat.getImageableX(), pageFormat.getImageableY());
disableDoubleBuffering(componentToBePrinted);
componentToBePrinted.paint(g2d);
enableDoubleBuffering(componentToBePrinted);
return(PAGE_EXISTS);
// }
}
/** The speed and quality of printing suffers dramatically if
* any of the containers have double buffering turned on.
* So this turns if off globally.
* @see enableDoubleBuffering
*/
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);
}
}
