Not your fault that there's an air of confusion about this thread, indeed! OP used the term "e pub", which I read as a reference to the
epub format. I've prepared documents in this format myself with a range of tools, though never Word.
The reference you cite, however, is about e-publishing using the
pdf format. Recent versions of Word – I think that's vague enough to be safe – include a Save as Adobe PDF command. I've only used this when I've needed to distribute documents with .eps graphics, so I don't know what pagoination options it provides.
Hope this clears the ground, so we can now wait in case OP politely gets back to us to close or continue the thread. If his problem is solved, so much the better. If not, we need to know exactly what he's trying to achieve and how he's setting about it.
