HP's are the best, hands down. And avoid Lexmark at all costs.
I would say get a cheap(well, the cheapest you can find anyways) HP laser printer. You'll probably be printing a lot of cases, etc. for class, and laser printers go faster, the printing is easier on the eyes, and like you said, it prints "dry" so no smudging.
If however you're gonna want to print photos or lots of fancy graphics and pictures (can't imagine why, in law school), get an inkjet.
