Picked up a ScanJet Plus. Seems to be in working order. Port is labelled PARALLEL I/F. Takes same input as a printer (centronics 25 pin). It does not respond with the driver I downloaded from HP that should be the one it requires. Win95 can not find the device. The system did not come with a card, I'm wondering if anyone is familiar with this scanner and can tell me what I need to set it up?
