I have an HP477fdw. It's a wireless, full color, full duplex laser printer/scanner/copier. I bought it 7-8 years ago. The ink is expensive but I don't use it enough to be concerned about it. It's great - I can print wirelessly from any device in my house and can scan directly to my laptop.
You can also do things like share it over the internet and print via an email address but I don't do that because it seems like something that could get exploited. It's honestly hard to imagine any situation where it's useful for me to print something when I'm away from home and have the printout waiting for me, but I couldn't wait until I got home and print it then. The only real benefit I can see, and even that is limited, is being able to allow friends to print a document for me. It's hard to see how that offers anything over and above sending me the file so I can print it myself.
