For me, it stems from the experience that novice users have administering their OS. An Ubuntu instance can be relatively easily installed and set to run a browser and have an 80% functional computer. Then it comes time to try to configure peripherals, and the printer is the primary one from what I’ve seen, and novice progress stops at that point.
