Hi C-Lo D,
You can give feedback to Apple via Numbers > Provide Numbers Feedback.
Assuming the hundreds of wedding planning apps available for the iPad and Android devices are downloaded and used, then it seems many people are not nearly as paper-based as they were just a few years ago.
Having said that, it would be nice if Apple beefs up print capabilities in Numbers 3. They have suggested they will do just that, in the support document linked to in Ian's post. Specifics are scarce.
However, as I said upthread, if you need to print out a lot of things on paper or to pdf in a traditional static fashion with precise margins, etc., then you're better off with Numbers 2.3 or Excel. Those products, however, don't play well with mobile. And, like it or not, mobile is on the rise.
