Thanks so much for confirming the color management bug in the B8850 driver. I've been driving myself crazy trying to figure out what I must have done to get the terrible color you describe.  I'm using 5x7 Ilford Glossy on an XP box with my B8850, so its not just 4x6 and not just Win7 64-bit.  As of the end of August 2010, still no updated driver from HP and, as you observe, none likely forthcoming given HP is leaving this market niche.  Too bad.
