Under Scrutiny: Four 1200 dpi Scanners

Speed At 300 And 600 Dpi

At 300 dpi, the differences in speed are much smaller. The D1250U2 operating on a USB 2.0 connection is the winner, followed closely by the Astra 4500. The slowpokes are the HP, Epson and the D1250U2 tested on a USB 1.1 interface.

The USB 2.0 really only comes into its own from 600 dpi upward. It is then that the D1250U2 greatly outshines its USB 1.1 rivals.
