Laser printer. I got an ink jet and it smears like crazy.
I used the printers in the law library....for three years. Never much of a problem. They were huge and modern...probably cost about $10,000 a piece, so they printed really well, and much better than anything I could have hoped to buy myself. Sure, I had a cheap printer at home, and in a pinch, it did the job. But, seriously, I can't even begin to describe the extent to which one does not need a ridiculously expensive printer. Even when I printed at home, on my $100 HP, the print quality never seemed to impact my grade.
Best advice: there is nothing "law school" related for a gift that will somehow magically elevate your friend to superstar status. Get him/her something meaningful between the two of you, that he/she will appreciate, as those are the best gifts, regardless of whether the person happens to be starting law school. There are no books, etc, that make good gifts, because pretty much everything is available electronically, or else dictated by the requirements of particular classes. What would you get the person if he/she was about to embark on a 2-year trip throughout Europe, start a new job, get married, or any other significant life-event? Law school is a big deal when you start, and it is a significant life event, so go with your heart, but don't try to find something "law-school" specific, or else you'll just end up getting him/her something that he keeps on the big, disheveled pile on the bottom of his/her bookshelf.
