While in calibre main screen, highlight the line your book is on and then hit "c" (for "convert"). At top-left (input) is your book as EPUB. Change top-right (output) to PDF. A new screen pops up. On the left column, second from bottom, are a kazillion things you can change to your liking, including header and/or footer design, paper sizes, fonts, margins, font size, table of contents. You can add "odd/even offset" for your own use, but this does not work for Amazon uploads. Best regards, Pop
