While everyone probably should learn something about their devices, the defaults you provide to users should be good ones.

Drawing a line can be hard, but clearly the basic font should be contrast-y enough so that most people can read it, no? The user can control the defaults of many things on their devices, but we shouldn't require them to change settings to have a good experience. We already customize websites a lot.

I think it depends on the goals of the print version, but people spend a lot of time picking fonts and styles so things look good on a screen. I take this as saying you should supply the same type of attention to your print style sheet.
