I have "cropped" an image using the following CSS:

div.crop {
height: 200px;
width: 200px;
overflow: hidden}

div.crop img {
margin: -0px 00px -0px -50px}

(div class="crop")
(img height="200" src="photos/test.jpg" class="crop")

For purposes of this post, I have replaced the carets with parentheses. Anyway, the script works -- on the screen, that is. My problem is, when the page is PRINTED the images appear in their original uncropped size. What script should I be using?
