[filmscanners] RE: Epson Perfection V750-M Pro Scanner,

["LAURIE SOLOMON" <LAURIE@ADVANCENET.NET>]

Jim,

Sort of a natural mistake since most people associate all scanner drivers as
twain drivers, which most were when all scanners were 32 bit.  Epson
probably did refer to the driver as a "64-bit driver" without bothering to
distinguish between twain based drivers and WIA based drivers, which
Microsoft has moved to for all their versions of OS since Vista.  I am not
sure if the drivers for Macs are twain or WIA or something else and if there
are 64 bit Mac drivers available or not since I do not use a Mac.  It may be
that the new Mac OSs have opted to use WIA drivers as well and that one can
use said drivers to work in 64 bit on their systems.

I was not trying to put you or anyone else down for the confusion but was
merely seeking to maintain some clarification of the various differences
between ASPI layers, Twain drivers, and WIA drivers as well as their
relationship to SCSI and USB interfaces and 32 bit versus 64 bit OSs and
drivers.

Laurie,

I could be wrong calling the Epson driver a 64-bit twain driver.  If
memory serves me, Epson referred to it as a "64-bit driver".  I did not
ask for it as I was, and still am, on 32-bit machines - mainly because
of the Sprintscan 120.
