git clone https://github.com/Kaporos/mdbook-paged
cd mdbook-paged
cargo install --path .

Add this to your book.toml to run this tool on build :)

[output.paged]

Your PDF output will be placed in book/pdf/output.pdf

By default, the pdf will be built only if GEN_PDF env variable is set.

GEN_PDF=1 mdbook build

if you want mdbook-paged to run either is env is not set, just add

[output.paged]
always=true

and pdf will be built automatically at each mdbook build.

If you want to inject your pdf to the html website print feature, just enable the config like this:

[output.paged]
inject-html = true

And then your pdf will be placed at book/html/output.pdf and will be accessible using html print feature !
