Current PDF export mode rom revealjs doesn't work reliable on most browsers. For example on Firefox you will still get garbage resp. wrong page breaks in the printed results after activating this mode. Well, you'll find a warning note about this flaw in the documentation, but it's IMHO still a very disappointing behavior. 

I would therefore prefer a more reliable solution, which provides reproducible correct results in arbitrary browsers.

This can be realized in practice by integrating [decktape](https://github.com/astefanutti/decktape) resp. [puppeteer](https://github.com/puppeteer/puppeteer), [playwright](https://github.com/microsoft/playwright) or another similar mechanism into the CLI-tool for the document processing to generate a PDF-document beside the HTML-output and just add a download button in the HTML-menu or -toolbar instead of the present print style-switch entry. That's the way, how for example [slidev](https://github.com/slidevjs/slidev) handles this task in a much more reliable manner (see: <https://sli.dev/guide/exporting#pdf>).
