LaserJet Pro 400 M401n wireless problem

Question

Provided paper instruction booklet and CD indicate that this model can connect via a WiFi home network and this is why I just purchased it. After hours of trying myself and then forever waiting for a chat window (which I gave up on) I finally searched the web for a telephone number. Rep said this model cannot do this but offered no explanation as to why it was advertised as being able to and why the documentation and CD reflect it can do, other than to say if I had purchased directly from HP, I wouldn't have had this problem. Before I waste anymore time on this, can anyone who actually KNOWS the answer tell me if this is possible and why there appears to be this problem with the documentation? Thank you so much. PS- if appears to have a wirelss button right on the control panel as well as the documenation refers to.

Thanks David,
Since having told Verizon home phone I had had enough, I brought in a Home Router with WiFi but had to mount it in the basement where the Internet connection comes in. My office is upstairs two floors up at the other end of the house. I wanted the HP Printer to print via the Wifi so my wife (or anyone else) on other levels of the home could print to it via WiFi, as well as myself from my smart as long as I was in range.  No easy way to hard-wire Ethernet or coaxial to my office without tearing my home up and obviously impractical for me to go two floors down into the basement to retreive any print-out, which is why I chose what I believed to be a WiFi printer. 
I am firm in my belief that the advertising was (surprise) inarticulate and now know that I am far from the only one who got caught in this thing. The instruction manual was for this model and the truly wireless model and was likewiese incredibly inarticulate (as seems to be the standard anymore-sadly) and this model does come with the wireless button, all of which led to understandable confusion on the point and the subsequent multiple hours of my time wasted while trying to determine the truth.
Too much of a hassle and additional time-burner to box this thing up and swap it out, I'm already hours behind. I appreciate your attempt to help and still believe there may be adapters or other solutions but I can't invest anymore time in it right now.
