Java 1.8 - Rendering Images To Printer / Result Is Not Good

I have some troubles rendering images to the printer, any resolution does not work, even 72 in PDF printer does not work, the image is crappy.

I use the following code but the result is not good. I mean the image quality is not acceptable.

img=new ImageIcon("c:\test\m.jpg").getImage();
scale=72/300d;
g.scale(scale,scale);
g.drawImage(img, 0, 0, (int) (img.getWidth(null)/scale), (int) (img.getHeight(null)/scale), null);

I've also tried :

img=new ImageIcon("c:\test\m.jpg").getImage();
AffineTransform aft=g.getTransform();
double scale=aft.getScaleX();
g.scale(scale,scale);
g.drawImage(img, 0, 0, (int) (img.getWidth(null)/scale), (int) (img.getHeight(null)/scale), null);

The result is the same even if I change the image, very poor and unacceptable!
