I don't know if I should give a full review so far. I really like everything I've used about it. It's really easy to use. I've done duplex printing, but not duplex copying, and I was very happy with the results. I don't know which ink it used, but it looked fine to me. Why does it matter?
I haven't faxed or copied yet, but the scanning works great. I've also printed directly from a memory card... pretty slick interface and the picture came out great without tweaking.
