I've seen others post with this issue, and I've tried some of the tips without luck. I print from LR CS6, and am unhappy with the slight tint of B&W prints. I've also seen a post where someone said the Pro-100 uses all the colours for B&W, and therefore the tint is unavoidable. Does anyone else use this printer for B&W prints and don't have this issue? If so, how do you avoid this issue?
