Better image quality than scanning photo prints - Photo prints are very low resolution, scanning them even with a high end photo scanner will still not provide you with a high quality digital image like scanning the original film will.

Fast and efficient, Saves time - High speed scanning: 24 sec./frame @ 6MP, fast scan speeds will make quick work of all those boxes and boxes of old negatives. Once digitized, users can share them countless times over with friends and family or even make print reproductions of old images that may have become lost or faded. Using the fast 6M setting, your digital output will have high enough quality to make 300 dpi prints at 10.0 x 6.7 inches (25.4 x 16.9 cm) in size.
Makes scanning easy & relaxing - The most convenient and easy to use 135 batch film scanner, simply load the films, set up the software with your particulars and select scan, now you are free to do other things instead of being tied to the computer.
Compact Size - small desktop footprint, takes up half the space of a conversional flatbed scanner.
