Hi @DArcher - are you using legacy dashboard or modern Lakeview(AI/BI) dashboard?
In the legacy one via notebook, there is no such direct way to export. You will have to do custom python script perhaps to write the output in html and then print to PDF. (Nasty it is, not sure of any better approach).
In the Lakeview Dashboard, you can use Share, Export to PDF.
