like the scanner and copier, everything works great. Printing function is good, my concern is why, when I print in all black in white, do the color ink cartridges all diminish in volume (and all are emptied at just about the same time)? Because I want to act responsibly, I return the "empty" ink cartridges, then they are no doubt refilled, rewrapped and resold. Thus I am participatory in HP's greedy scam.
