Our world would be different because without the printing press we would have no books, so school would be different and probably more difficult. Without the printing press we never would have printed bibles so church and any religious studies would be different (and probably more difficult) AND of course we would have no newspapers so there would be less advertising, and nothing to read on Sunday morning.

No, it's not correct!
A correct version would be "we are waiting for your feedback" - you need to add "for". You wait for something, - the " for" is necessary.
Alternatively you could say "we are awaiting your feedback" - then you don't need to add for, (but it's "awaiting, not waiting")
