They have have gone the way of trackballs* and Hercules graphics adapters for most of us, but did you know you can still buy a variety of Dot Matrix Printers down at your local Office Depot? They aren't cheap, either—the lowest-end Epson is $300. They're still used in a lot of places to print out receipts, reports, and forms in systems that haven't been updated since the early '90s.
Some stores even have new color dot matrix printers like the picture Okidata Microline 395C, which you can add to your office for just $1,164. (Available exclusively in Nicotine Stain beige.)
Is there a good reason you're still using dot matrix printers in your workplace, besides an affection for their cicada-like screams?
* Sorry, trackballers, I can't resist an opportunity to tease.
