The return of the dot-matrix... (Score 2, Insightful)

I'm seriously considering taking home one of those black ink dot-matrix printers sitting in storage at work, which I could have for free. They're industrial printers that last, and for just black and white printing that will eventually get trashed, it would be cheaper than my HP inkjet, which is the only printer on my small LAN at home. My wife and kids are killing me on inkjet ink. I know I'll need to attach a print server to network it, but it still may prove to be useful.
