How do you Print your Digital Pictures?

Registering a digital camera, the manufacturer asked me this question. There was no option to say I never print prictures. In fact, I can't figure out why I'd ever want printed pictures. Pictures are just a way to store the image on paper. Why not just store them digitally? Is this some kind of hard-copy thing? Make backups. While I can understand not wanting to read very long texts on computer (say, books), I can't think of any reason to print pictures. Alright, I can think of reasons (say, Christmas cards), but I've never done these things and I don't forsee it in the future. Since the manufacturer didn't have an expectation that I would answer "I don't" to the above question, how can they ideally serve me?
