Wireless Printer in a dorm room question

[graylocks]

i've been waiting for a good deal on a laser printer for my son living at college. i assumed wireless since that's what we have at home and in his small college room he could stick it anywhere. then i began to wonder if wireless in a dorm is a good idea. at home no once else is on our network but in order for my son to use the printer wirelessly he'd have to be on the wifi in the dorm. would that mean that anyone else on that same wifi network would have access to his printer or is there something in the printer set up that would let you password protect it or something.

as mentioned in a thread a few days ago, Staples has the Brother 2240 on sale today only for $59 which is the price point i've been looking for. it's not wireless and i'm trying to decide if i should get it or hold out for a wireless like i originally thought i wanted.
