Two things...
32bit Servers can host 64bit printer drivers and vice versa. The trick is making sure the drivers are named the same. I've found that when sites like HP release their drivers, they release the 32/64bit drivers in tandem. So I always download both and install both at the same time.
More recent versions of kix support the @onwow64 macro to determine 32 or 64bit OS.
Thx for your reply
So do i have to install 2 printers with 1.)64bit and 2.) 32bit
or 1 printer with 32 and 64bit?
