A:AnswerLove this printer so far, it offers many features, most of which I do use, like the Print(of course), scan, fax. I haven't been able to try all the printing features yet, but I'm looking forward to working with this printer. The set up was really easy, and connecting to wifi as well, including printing from our cellphones.
