spatten said that Leanpub output is currently "print ready as-is." My question was, when a Leanpub document is printed, what ensures that there aren't distracting bits of extra white space and other annoyances that often require a human eye and manual adjustment to avoid? If you're seeing rivers on a Kindle I'm guessing there'd be the same problem on paper.
