Thanks to you both for your replies.
I should have explained that I have already seen 'Getting Started with Adobe Digital Editions', an epub document that comes with the software. It is only nine pages long, more of a quick guide than a manual. I had expected that there would be more to the software than is covered there. Perhaps there isn't. (To explain a little further: I was looking for a way to cause epub pages to print or display like the pages of the original book, but couldn't find anything about printing beyond. That feature is present in the Bluefire Reader for iOS devices. I tried printing a particular page using Ctrl+P and specifying the page number. The page printed, but it was spread over two sheets of A4 paper and the page number was not printed.)
