I inherited an Canon Pixma MG3600 from a friend who got a new printer of her own, and it's been impressively stable for years now.
A really solid printing experience on Linux; I'd say "plug and play" but I've got it set up for wireless printing and it worked immediately without plugging in!
I've not tried the scanner on Linux but it worked on Mac out of the box without proprietary drivers so I can imagine the same for Linux.
