Will the Mini-Scanner Work with the 2004 Model Year Prius?

Unfortunately, no. Toyota have changed the way that their scanner gets at diagnostic information in the 2004 car. Information mandated by law is (presumably) still available on the ISO 9141-2 bus, but all of the interesting stuff has been removed and is now accessed using a CAN (Controller Area Network) bus. There are no definite plans at this time for a Mini-Scanner for the 2004 Prius. Connecting to the CAN bus is not a problem as it still appears at the Diagnostic Link Connector. The difficulty will be discovering the format of the messages that are sent on the bus to get information from the car.
