I believe the situation with the Windows 2000 driver for this printer is
that it will work with XP as well. That being the case, it probably will
work with Vista 32 bit. However, no one has revised the driver so that it
is properly tested and internally "signed" as Vista compatible. This
process is one usually initiated by the printer maker. In this case, that
would be Epson.
That being said, the news is not totally dismal.
If you start Vista and use the method to see the start menu, you can
select disable driver check on start-up. If you do that, the driver might
install properly. However, each time you start Vista you have to again
disable driver check. That is definitely not a good idea. However, it
might be worth doing to check on the suitability of the driver. Having
done that, try e-mailing Epson support with the results of the test and
ask if and when a Vista driver might be available.
Also, set a system restore point before you start. The system will
probably do that anyway but I am a "belt and braces" for greater
assurance sort of guy.
Good luck.
