As far as I know, the current workflow for exporting slides to PDF is as follows (http://stackoverflow.com/a/34168948/2184571):

jupyter nbconvert --to slides --post serve /path/to/your/notebook.ipynb

Append ?print-pdf to the URL:

http://127.0.0.1:8000/<some-title>.slides.html?print-pdf

Finally, use browser's print dialog to print to a PDF file.

Would it be possible to simplify this? For instance, so that something like this would work:

jupyter nbconvert --to pdfslides /path/to/your/notebook.ipynb

or

jupyter nbconvert --to slides --post pdf /path/to/your/notebook.ipynb
