For the last few days I've been trying to print a PDF, it's the first time I really try to print a PDF since I got Windows Vista. My problem was bad images, they were fine in excel and word but once printed trough Adobe PDF, bioPDF or PDF995. It all came out the same, pixilated.

After many tests and some research I came across this article written by Julie Shaffer of "Center for Imaging Excellence". It basically explains how to avoid bad PDF. But her suggested configuration did not quite fit with my favored PDF printer, bioPDF. The "Output Protocol" "Binary" does not work with my computer configuration, I had to use "ASCII". My two main errors were also that my images were less than 300 dpi and had transparent backgrounds.
