Please note: your scanner manufacturer is not Acer, it's Relisys. model # is correct. Also note, I doubt this scanner was ever supported in Windows XP as Windows XP does not get along well with many parallel port scanner models.

In searching our site, only Avec II E330 Windows (older os's) drivers appear......
