Cool. Keep in mind that you'll need to buy ink immediately for the printer. They always ship a "sample" of ink with the printer and it's good for about 20 pages. Plus, if it's a bubble or ink jet, you'll need to make sure you use it at least once every month or so, or more frequently, since the jets will get clogged if they dry out and then you will have to buy a new ink cartridge/heads. If you're like me and you print once every 6 months, an inexpensive laser printer may be better.
Oh, and don't forget: It's free cause of all the value-added software. Most of that is crap. We reimage every machine in house and you may want to format yours as soon as it's received since they'll load on norton anti-virus (A rip-off for your wallet) and who knows what else.
Get it back to base WinXP, or Vista, load AVG anti-virus (the free one with free automatic updates), and then load OpenOffice (free MSOffice-like app). Make sure you do automatic windows updates, too.
