Well, my two laptops were both acquired used, so I didn't pay as much.

I wouldn't haul a printer around. Portable printers generally aren't worth the trouble. And with wireless, if there's a campus network, you can just print to a "public" printer or something. Or, if you have the right sort of router and a DSL or cable connection at home, you may even be able to use VPN to print to your home printer.
