I'm looking at printers again. Seems my Epson R2400 has given up the ghost. The Canon PRO9000 looks good, except, it only uses one type of black and no gray inks. My Epson and HP both use 2 types of black and 2 types of gray. I worry that either or both the photos and text will not be satisfactory. Anyone use the PRO9000 or knows why just one black ink?
