Its just college
You are going to be too busy working/studying (assuming you intend to graduate) to really worry about such things imo.
When furnishing my dorm room I always just went for functional and cheap.
Anyways, some advice. Wait till after you have slept on the bed before you decide on a mattress topper so you know what you need. Dorm room beds/mattresses vary drastically. The ones at my university are very firm and rigid so I got a nice memory foam mattress topper (40$ at Target) and it made a WORLD of difference.
For comforters. Just get what you like but remember that it NEEDS to be machine washable. Things tend to get dirty in dorm rooms fast.
For lighting I would make sure to get something that you can reach from bed on the chance that you spend time reading there. It is a pain to have to get up to turn off the lights.
Buy VERY distinctive towels. Maybe beach towels? From experience I can tell you that generic stuff tends to get stolen/adopted by others.
I wouldn't worry about a printer. Generally it is much cheaper to print on campus, though it varies.
I assume your apt comes furnished since it is a dorm? I recommend not buying a lot of furniture because it will get VERY crowded VERY quickly.
If your apt doesn't have a refrigerator invest in a small one, even if you have a meal plan. It is sooooo convenient.
