Usually I just print with Unix command lp. I could write a
script that would shift the image to the centre of the page
before printing. Never needed such a thing before. I'm used to
application creating EPS with images centred.

I never encoutered software that behaves in such a silly matter.
But I take your word for it.

That's a sound suggestion.
Why not allow for the user to set the papersize? Instead of
having in the body of dev.copy2eps the following line:
oc$paper <- "special"
you could put this:
oc$paper <- "special"
The way it is now, I *can* specify the paper as an option, but
it is ignored in the body and replaced by "special". I think
it's annoying to have options that don't work. And being used to
working with Unix, I don't think you should "protect" people by
limiting their options.
