Well, you are getting a multi-page TIFF with OCR, not a PDF. HP's garbage software died on me leaving me without a free means to make PDF files. The only formats I can do are TIFF or XPS, and Lucide cant do XPS yet sooo

(as for the gotta go back to XP thing above, I need scanner support and Office Document Imaging)
Edit: Its done, 15.8MB, what I do with it now?
Edit Edit: The .xps is 6.99MB, but not sure if OCR was preserved?
