I remember when color printers first hit the home market. They were incredibly expensive, and the cartridges were, too. Now, the cartridges are still pricey, but you can get a decent all-in-one printer for next to nothing.
When photo printers hit, it was really a big deal. I know how thrilled people were that they didn't have to depend on the drugstore or some other place to do their prints; they could print their own pictures. And photo paper is affordable now, so it's been a good innovation.
It’s even a cinch to print address labels and even wedding invitations at home with a color printer.
