A:Answer Dear Wondering;
I did some research, too, and did not find much information on it. The way to look at it is this model goes along with the HP Envy 7600 series; this means that they all work alike, they all have the same functions, etc. In my professional dealings with this model, selling it, and setting it up, it works great, prints fast, and it is easy to set up. It only uses 2 cartridges, so you'll be saving some $$$. I would buy it again.
Best of luck.
