The shells do no seem to support this very well.
Normally I would do this kind of tasks with expect.
My experience is that one has to mimic the time behavior of the program that
expects something from standard input.
You may try replacing the simple printf by this subshell expression:
Code:
(sleep 1; printf "\n")
