question: Book print or `pdf` version?

[Afifurrohman]

I think is good to have a print or pdf version like mdbook does.

See #1070. I agree that this would be a useful feature! There is already a prototype implementation in #1232, maybe this works for you?

like mdbook does.

Could you post a link to some documentation of this feature? Maybe we can reuse some of its implementation.
