I really think this is something that we should be able to figure out
without having to throw the burden to the user -- throwing up a prompt is
really no better than the current status quo. At the end of the day, IMO a
good user experience is that when the user says they want to print
something, they get a printout that makes sense. If the web developer is
actually thinking about printing and has a way to signal that, then the web
author is probably in a much better position to say what actually makes
sense to print. If the web developer hasn't thought about it, then we (the
UA) are the next best equipped to figure out what makes sense to print vs
what doesn't. The user is in the worst position to make that decision in
most cases, and has limited feasible interactions to signal their desire as
to what the output should look like.
