Sure there are ways to do it without PS, but I'd bet money on it that this particular one is photoshopped.
I think what I suggested it right because:
1. The photos are the right type for a portable printer.
and
2. If you look at the gap below his hand it represents at least 20% of the overall height of the image, and in the photo the guy is holding (in the photo of the photo) it looks lore like 15% so the shot is not set up identically. If it were shopped that wouldn't be the case.
