Epson WorkForce 645 All-in-One printer
Despite PDFs and email, the paperless university is as much of a pipe dream as the paperless office. While not the cheapest multifunction printer available, the Epson WorkForce 645 ($149.99; $99.99 at Amazon) offers an excellent balance of price and performance, and its compact design means it won't take up half your dorm room. It prints at up to 15 ppm (one-sided, black), does automatic two-sided printing and scanning, and comes with a 30-sheet automatic document feeder for batch scanning.
Besides wireless printing from computers, it supports Apple AirPrint and Epson iPrint for printing from mobile devices. And it comes with full-size ink cartridges, not the low-capacity "starter" cartridges other printers start you off with.
