MadMonkey: did you try a different software? You should be able to export your office-files into a .pdf for example and then open and print it using the adobe reader (or better adobe acrobat if you have this commercial software). And then, of course, you should try it on both printers :-D
if the problem isnt solved or at least concretized, i would suggest also to check if the paper tray is adjusted correctly...
