For Windows 8.1 and also Windows 10, what can reproduce EPUB files as a PDF, with no changes and loss of quality?
I ask NOT about Calibre and ePub Converter, which can transform an EPUB file into a PDF, but which uselessly disfigured the original EPUB's font, format, and structure. Specifically, the text in the PDF becomes disorganised; one original paragraph (on the original page) is chaotically split into different pages. All text layout and formatting are lost: paragraphs are compressed together, headers shrink in size to cease its appearance as a header, etc.
