filmscanners: 35mm film versus medium-format scan quality

[Vuthy Chrun]

I would like to hear your experience and opinion on the difference (if 
there is any) between scanning a 35mm negative or slide with a 4000 DPI 
scanner and printing the image on a 1200 DPI colour printer versus scanning 
a 6x6 negative or slide on, let's say, an Epson 2450 and then printing the 
image on the same 1200 DPI colour printer.
