@ross That printer does duplex printing - I know as I have it. (brother makes several models, the article is about whatever is on sale, I waited until the week the model with duplex as on sale and thus the cheapest option).
You can get brother lasers with color as well, but they are never the cheapest thing on sale. For most people though they are better off sending their color printing needs to the nearest store and picking it up on the next errant.
