I was very happy with what I managed to screw out of my HP B 9180 in black and white, if not colour, but HP chose to abandon the system. I have printed nothing since then.
It's problem was that it had to be left switched on 24/24 so that it could run its own cleaning programme each day and keep clogging at bay. It never did clog, but did enjoy drinking ink!
I still have it, taking up desk space, but it's too pretty and heavy to carry out of the place... I wish there was an alternative b/w set of inks it could use, but as it isn't supported, I guess it wouldn't be worth the risk of spending more time or money on it.
