Help!!! Image print problem

[sam patel]

hi,
I want to print an image using JAI(Java Advance Imaging). I have something which scales the image
first and then prints it out. It prints the image, but the resolution of the Image is horrible.
The image comes out so blury it hard to see. Can anybody help me with this problem.
Any help is always appreciated.
Here is the Code.

import java.util.*;
import java.awt.*;
import java.awt.geom.*;
import java.awt.image.*;
import java.awt.print.*;
import javax.media.jai.*;
import com.sun.media.jai.codec.*;
import java.awt.image.renderable.ParameterBlock;
import javax.swing.RepaintManager;

}

g2d.translate(f.getImageableX(), f.getImageableY());
