You didn't ask a real question; it's not my problem if you don't
like the answer.  You can't possibly infer what I know from this
kind of exchange.  I've done this so often that my eyes glaze
over at the thought of it.

The printer manuals have this information; the reasons for their
choices are valid for them, so that's all you need to know.

In  my experience, most printers accept either; you tell them
what you're doing, either by hardware switches or in software,
and they are happy.  But that's not really going to help you.

Asking about "most printers" simply makes no sense.  Most days
here are sunny, but that doesn't mean I'll never need heating.
What matters is the behaviour of the specific printer that you
need to deal with.  Read its documentation, then write your
code.

And if all you can do is be abusive when you get an answer you
don't like, then you need to grow up a bit.  Nobody owes you
anything, and nobody has to give you answers that you'll like,
especially when you don't ask good questions.
