I'm using OpenOffice, so it comes up mumbo-jumbo for me
As long as the original is better quality than the images that you showed, then its 95% perfect (there is always room for improvement

)
BTW, is it cheaper getting a printing company to print you out a few thousand letterheads, or using your own printer+ink? I'm sure you'd want to print @ best quality; which will chew through your ink quickly.
