I had the same problem with my 693C HP printer and went back to using PAF 4.0. However, our computer crashed and I lost both programs. As a result, last week Idownloaded the updated 5.1 program. Technicians had told me the unicode was the problem. It is now possible during the downloading process to not include the unicode. Since our records are all in English, this was no problem. My printer now prints at the same speed it did with PAF 4.0. Perhaps this will work for you as well.
