People this is NOT a printer problem or problem with the ink cartridge. I had this happen a couple of months ago and now it is happening again. I even bought a new printer and the same thing happened so I knew then that it wasn't even my printer!!!!! Somewhere I found someone who told me that it is because of some update that the computer did and the only thing to do was wait - I waited and in a couple of weeks it came back - it is however happening again and it is because I think I updated my Iphone through ITunes - it loused up a bunch of things on my computer and it is now not printing in black again - it is infuriating and frustrating - does anyone know something to speed up the process of getting it back to printing in black - I'm sick of this!
