I'm not sure when it happened but my HP deskjet 970 has been out of commission for a while. It went through a phase where it would take an hour to print one line. Lately it's not printing because it insists I change the color ink cartridge. I only want to print black, and black is full. This used to be no problem, but someone got greedy at some point.

I'll try to install this update and see if I have better luck.
