A "print PDF" might be considered to be any PDF that gets printed to hardcopy.
An "ePDF" would be one of those nifty "interactive" PDFs.
Bookmarks, links within the PDF, links to other PDFs, show/hide fields, form fields, comment and markup annotations, and rich media (to mention a few).
Now if you create a PDF via a File - Print and use the Adobe PDF virtual PDF you would have to add the neat stuff with Acrobat.
Nothing there upfront. Such a PDF is often refered to as a "print PDF".
Be well...
