Sorry to disappoint but Docusaurus does not provide that out of the box, however some devs built that as community plugins, but can't tell how qualitative it is

Sorry to disappoint but Docusaurus does not provide that out of the box, however some devs built that as community plugins, but can't tell how qualitative it is. We believe a documentation can be much better when it's made interactive, so Docusaurus favor interactive experiences over generating a static PDF export. But we'd like to support PDF exorts in the future to please people like you that might have a different opinion
