Don't know what WIFI is but here's my pennyworth about Epson v Canon. My Epson recently gave up and I've replaced it with a Canon. I much prefer the Canon as I am able to print card which I was not able to do on the Epson. The images are much better too but that may just be because the Epson was 3 years old and things change very quickly in the world of printers etc. The ink seems to be lasting longer too.

I know this doesn't answer your question specifically, but gives an overview of the brands
