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



I would check again on the 64-bit twain driver.  Epson may have developed a
proprietary driver for the scanner but I sort of doubt it was a twain driver
since there were never any official standards set for the 64 bit twain
driver by the twain working group consortium even though they talked about
doing so and there was never any implementation of an official 64-bit twain
driver although there may have been implementations of 64 bit drivers for
scanners by third parties (e.g. Ed Hamrick) manufacturers as proprietary
items.  It is quite possible that what you got was a 64 bit WIA interface
driver which allows the scanner to work with 64 bit Windows Vista machines
and maybe XP.

I see where there is now some discussion online about standards for a 64 bit
version 2.0 twain driver set of standards (version 1 discussions were
abandoned a few years ago); but the discussions do not seem to have reached
a firm enough stage that there have been any fully implemented instances of
such a twain driver that are working drivers issued by software developers.

I have an Epson 1600, that's older than my Polaroid 120 and Epson has
provided 64-bit twain drivers for it.  But you're right, the 120 will
have to stay with a 32-bit XP machine.
