I also like to print out A3 posters for my kids and these printers can do that, whereas I'd never buy a huge A3 printer to have at home.
US 7-11's absolutely do not have this service, and you're lucky if you find a grocery store that has a photo copier these days (was somewhat common in the 90s).
At my local library, prints are $0.05/page, vs. $0.15/page at my local commercial print shop.
There's also reprographics places and most shipping stores do printing as well.
None of that is as convenient as a home printer, though. If you can get a decent color laser and lightly use it, it should treat you well for quite some time. Inkjets don't really like light use though, although I have fond memories of first page time on the ancient Deskjet 660C and 720C.
