Bests & Worsts Reviews from Amazon

I followed the instructions to connect a printer to WiFi a few times, and it never worked. Not from the smart phone, not from the laptop ( I have MAC). Tried to connect manually, got an error too, however somehow printer got connected since I am able to print using default MAC driver. Scanner does not work. It is ok printer actually for $$ spent, but looks like Canon folks never tested their own instructions.
