Catablog Lightbox Not Printing Images

I am having the issue of printing the Catablog lightbox contents (image and description). I have figured out that the Previous and Next button overlays are obscuring the image from printing. I would appreciate any help in fixing this. For an example of what is happening, visit http://mitchginn.com/house-plans/2689-sq-ft-%E2%80%A2-timblethorne/ , click on the thumbnail image, and try to print the lightbox.
