There isn’t a way to directly export a PDF of the Workflow “view” with formatting preserved, although that has been discussed and may be included in a future release. Or if you are interested in helping out, a development PR to add in this functionality would be welcomed. Many views could use this type of output.
The page can be saved in .htm format (“control+right-click+save-as” on MAC OSX) which will remove a bit of the extra formatting. You’ll end up with just the text, which may be enough.
