About Canon vs. HP. I have an HP 750, I printed a ream of paper (~500 pages, mostly b/w engineering HW solutions, powerpoint slides) before my first black cartridge died. That includes the printing of my roommates whose Canon models had all died. All three of theirs died, and needed replacement of the whole print assembly, not just the tiny little black cartridges, which are priced conveniently at $49.99. So one actually bought the new cartridge assembly, while the others mooched off me for a quarter. Canon's may seem cheap, but they're really really small, and are literally just ink, not the whole printing assembly, unlike HP. (Is assembly the right word?) I don't mean to be rude, but I've had great luck with HPs and terrible luck with Canons.
