_If_ gtk+ printing has to go through a cairo layer, I don't see why this
would be so.  Cairo should render the same content to screen as it does
to a PS/PDF file.  By explicit goal of the Cairo project, this _must
work_.

You could claim quite the reverse.  If print preview does not go through
App->Cairo->PDF->Cairo->Screen layers (would be only
App->Cairo->Screen), then users will not catch PDF/PS generation bugs so
soon, they only see the bugs appear on paper, and then it will be
convoluted by printer driver bugs, etc.

Anyway, +1 from me too.
