I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic.

I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.
