|Do a search for "dot matrix" on ebay. Those are the ones with a typewriter-type ribbon. The paper was a continuous sheet with perferations so it could be torn into standard sheets. I know I've still got a few epson dot matrix around here somewhere.|
But you might look for an HP laserjet. The II and III were real workhorses and lasted quite a while. Some of the later LJs had problems with the rollers and would start pulling more than one sheet through.
Check the classifieds in your local paper under office equipment. You might find a good laserjet locally. Check any local auctions also, as well as thrift shops like goodwill.
You'll want one with a standard parallel port connector--not USB.
