CSS/Jquery to format printing of images

We have over 600 various documents that use html on top of images for the pages. Some are landscape, some portrait, but all print on 8.5 x 11 paper. Our screen version is perfect and uses % for placement on the page. When you go to print, they look perfect as well as long as the image is in the correct proportion. We have many issues with printing, blank pages before or after, pages not holding margins, images flowing to the next page, next image starting following, etc. I am looking for someone to write global code to cross browser force it to use portrait or landscape based on image ratio, use default settings ([login to view URL]), and print on single page. Looking for someone who really knows printing with css, please don't waste both of our time.
