Steps to Reproduce

To reproduce this behavior, create an image, paint to the graphics object obtained from the Image.getGraphics()function, and then copy the image to the graphics object passed to public void print() by using Graphics.drawImage().

The following Java example reproduces this problem:


   import java.applet.Applet;
   import java.awt.*;

   public class PrintTest extends Applet
   {
       protected Color c[] = new Color[8];
       {
           c[0] = Color.blue;
           c[1] = Color.cyan;
           c[2] = Color.green;
           c[3] = Color.magenta;
           c[4] = Color.orange;
           c[5] = Color.pink;
           c[6] = Color.red;
           c[7] = Color.yellow;
       }

       public void paintDoubleBuffered(Graphics g)
       {
           Dimension d = getSize();
           Image i = createImage(d.width,d.height);
           Graphics tg = i.getGraphics();
           paintDirect(tg);
           g.drawImage(i,0,0,this);
       }

       public void paintDirect(Graphics g)
       {
           Dimension d = getSize();
           int yinc = (int)((float)d.height / (float)c.length + 0.5);
           for (int i = 0; i < c.length; i++) {
               g.setColor(c[i]);
               g.fillRect(0,i*yinc,d.width,yinc);
           }
       }

       public void paint(Graphics g)
       {
           paintDoubleBuffered(g);
       }

       public void print(Graphics g)
       {
         // to workaround:
           // uncomment the next line
         // comment the one after it

           //paintDirect(g);
           paintDoubleBuffered(g);
       }
   }
