So I got the SBS 2008 printer issue resolved (see here for some background). To sum up, while I was able to get the HP printer drivers in both 32-bit and 64-bit flavors, I could not get the Konica-Minolta 2300DL color printer to play nicely. The fix?
Install the printer driver locally on each machine.
Oh…and also make sure that the IP address is hard coded in the printer itself (I apparently was using DHCP mapping on this machine).
