Your problem is that ePub (and MOBI) are not page-based formats. They're flowing text. Printed page references don't exist in the files. Sorry.
edit: Hmm. More thinking... Perhaps there are applications that will add a page footer when printing. I don't know of one. I checked Calibre's e-book viewer. No joy. (Sorry again.)
edit #2: You might have to import the ePub to a word processor. Ick.
