HP Deskjet 970Cxi Professional Series Inkjet Printer + Duplexer+ Ink.  Always prints perfectly in black, but does not print color consistently - sometimes color appears on a printout, sometimes color prints lightly, and sometimes it does not print color at all (see printout pics). Duplex (double-sided) printing was also tested and works well.  Comes with black and color ink cartridges already installed.  Excellent cosmetic condition.
