Java: Component.printAll() problem.

Question

Hi.

I'm trying to print a JFrame using the PrintUtilities Class:

package util;
import java.awt.*;
import javax.swing.*;
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() {
    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 pf, int page) throws
                                                    PrinterException {
        if (page > 0) {
            return NO_SUCH_PAGE;
        }

        Graphics2D g2d = (Graphics2D)g;
        g2d.translate(pf.getImageableX(), pf.getImageableY());

        /* Print the entire visible contents of a java.awt.Frame */
        componentToBePrinted.printAll(g2d);

        return PAGE_EXISTS;
  }

  public static void disableDoubleBuffering(Component c) {
    RepaintManager currentManager = RepaintManager.currentManager(c);
    currentManager.setDoubleBufferingEnabled(false);
  }

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

This is a screenshot of the JFrame : http://img43.imageshack.us/img43/1980/48727815.jpg

And this is what the print (xps) came out to be: http://img526.imageshack.us/img526/9954/47028546.jpg

What am i doing wrong here?

Answer 1

Hi,

I get exactly the same result when attempting to print to an .xps, but it does print correctly when I choose to save as to the Microsoft Office Document Image Writer (.tif) or directly to my printer.

Does your target have to be an .xps file or were you just using that for testing?
