It depends what machine and who is using it. Fuji frontiers can scan at an optical 5000dpi with an output of 300dpi at the smallest. A Noritsu can scan in at at least 4000 optical dpi with an output of 72-96 dpi. Ironically, I find that the 72dpi is more versatile and more printable at larger sizes than the 300. I think it is that the actual size is larger at 72 vs the 300, therefore at "equal" dpi, the 72 prints better.
