@ross I've been very happy with the Brother laser printer I bought in 2006 when I started graduate school. It's still kicking.

Based on that experience, though, I recommended a different Brother printer to someone a few years ago. They had issues with it forcing early toner refills that it definitely didn't need yet.

Old models used an optical sensor of some sort to check toner levels, and new ones just count pages and throw tantrums when you refuse to replace toner when it says so.
