I doubt you'll find a normal digital camera that'll do what you ask, I'd use something like imagemagik or netpbm to manipulate the image automatically.

When I joined the bbc, they had a video camera linked to a framestore and a custom written piece of software that cropped the 4:3 video image and then added text and printed it onto a blank smart card. Apparently the system came as a whole, from the camera to the printer.
