Actually, the primary motivation of introducing a cairo terminal was
to support the generation of PDF data from the buffer contents
directly using the Emacs redisplay engine, even from a tty session
(i.e., without X server running), rather than supporting multiple
window systems.  Showing a print dialog, sending the output to a
printer, etc. will need another library or something, perhaps in a
window-system dependent way.

Do you possibly have some idea of "abstraction on a higher level"?
