There are a lot of comments here saying that printers and scanners are complicated! Really? More complicated than your microwave, fridge freezer, television? More complicated than your car?
Printers and scanners aren't complicated, it's just that we don't really need to use them much anymore... until we have to. 99 times out of a hundred I don't need to scan because I can just take a picture on my phone of any hard copy document. I don't need to print because people are happy to receive an electronic document by email.
If I never had to drive again, I'm pretty sure I'd forget how to operate a car after a few years. If I'd never operated a washing machine in my life, I'm pretty sure I'd struggle to put on that first wash. Every time we have a power cut, and my oven refuses to work, because the clock is not set, I just push buttons randomly until it works. Instructions for resetting the clock are just not worth remembering, as it only happens once a year or so.
There's nothing complicated about these devices. I used to bootleg VHS tapes by hooking up two player/recorders. That's a skill that's completely useless now. These devices are just becoming obsolete, so we don't bother learning how to use them. I'm pretty sure I'd be unable to start and drive a Model T Ford, and I don't see any shame in that.
