So the key is getting a printer that uses toner not ink?
Yes. What everyone has said. Toner is a dry powder, plastic on the outside, that melts to the paper as part of the fusing process. Laser printers use toner.
Inkjet printers use ink, which is a liquid, and it eventually dries out and can cause the nozzles to jam.
Overall, per page, laser printers are cheaper, and they're much more tolerant of intermittent use.
Laser printers are more expensive overall, and the cost to buy toner and other consumables is higher, usually. Color laser printers are particularly expensive for the toner...I wouldn't be surprised if per page color laser could exceed per page color inkjet.
Laser printers have some disadvantages. They're not really portable. Moving them after the toner has been installed isn't a great idea. They're also not great in dusty environments, especially if the dust is conductive. They're pretty crappy for photos, generally speaking.
Old HP laserjets, 4 or earlier, are great, but I don't know if anyone still makes consumables for them. I wouldn't buy a newer HP. I did buy a new color Xerox, and so far it's been great. My last inkjet was a Canon, and it was great. Color photos were beautiful.
