Well I got it working. I had to add a inch to the top margin which doesn't make any sense. Because it was the left margin that was being cut off. But oh well its printing my covers properly now. And beggars cant be choosers.
*I added a inch to the left margin in attempt to fix it and that should of fixed it. But what did it do it cut off even more of the cover on the left side. Doh weirdo stuff. Then added an inch to the top margin which shouldn't of done anything but move the cover down a bit and what happens, it works.
