PrinceXML (Score 1)

I needed to layout a novel in a PDF. I've previously worked with iText and prefer not to construct a PDF one element at a time. I wanted an HTML to PDF workflow. I then tried wkhtmltopdf, but it doesn't support most of the hardcore design needs: hyphenation, widow/orphan control, alternating page margins, and page headers and footers based on the section of a document. PrinceXML supports all that. Writing only CSS, and based on html content, you'll be able to replicate anything a designer can do in InDesign. It's incredibly powerful and the time it saves in development effort more than pays for the high cost of the software.
