| **src** | _<empty>_ | The path to the to the OpenAPI specification resource or URL to be used. Resource paths adhere to [Hugo's logical path](https://gohugo.io/methods/page/path/). |
If you want to print out (or generate a PDF) from your OpenAPI documentation, don't initiate printing directly from the page because the elements are optimized for interactive usage in a browser.
Instead, open the [print preview](configuration/customization#activate-print-support) in your browser and initiate printing from that page. This page is optimized for reading and expands most of the available sections.
