Try this code and see if you are still having the problem.

import java.awt.*;
import java.awt.event.*;
import java.awt.image.*;
import java.awt.print.*;
import java.io.*;
import javax.imageio.*;

public class test implements Printable {
     final BufferedImage image;

     public test() throws IOException {
         image = ImageIO.read(new File("kittens.jpg"));
     }

     public int print(Graphics g, PageFormat pf, int index) {
         if (index != 0)
             return Printable.NO_SUCH_PAGE;

         g.drawImage(image,(int)pf.getImageableX(),
          (int)pf.getImageableY(),null);
         return Printable.PAGE_EXISTS;
     }

     public static void main(String[] args) {
         try {
             test t = new test();
             PrinterJob pj = PrinterJob.getPrinterJob();
             PageFormat pf = pj.defaultPage();
             pj.setPrintable(t);
             if (pj.printDialog())
                 try {
                     pj.print();
                 } catch (PrinterException pe) {
                     pe.printStackTrace();
                 }
         } catch (IOException ioe) {
             ioe.printStackTrace();
         }
