Just to give you an idea of what you might use this for (in case my OP wasn't clear), a studio photographer can set up a DSLR next to his/her LF camera. Now, since almost every DSLR has a Video Out port, you can take the video from that port and input it into the printer. You then print out the image to get an idea of what you're seeing, much as Polaroids were used back in the day.

Once you're happy with the print, switch to that expensive LF film stock and get the shot the first time!
