So based on this design concept I have to assume that they expect this printer to run on either batteries or wireless power of some sort. I don't mean to be too down on this as it is an interesting concept, but it annoys me when designers leave out things like power cords to make their mockup look cleaner than it actually is. It seems like a copout.
