If you want Enhanced Typessetting you must generate your ebook with the new ebook proprietary format KFX. Amazon generates this format when you publish books in their store or you do it yourself using a Calibre plugin.
I have a personal book that I would like to send to friends without publishing it in the Amazon store. I can generate a KFX format using Kindle Previewer, but I failed to try to upload it to my personal documents and sending it to my kindle email.
I'd like to share my book with my friends, but I want to make it easy for them to load the book on their devices. I don't want to teach them to use Calibre or to connect their kindle using a cable.
Is it possible to wirelessly send an enhanced typesetting book to a device?
