A Shortcode can be used inside posts / pages to show the PDF export buttons. The Shortcode is:
[wordpress_pdf_catalog category="full OR CATEGORY_ID" taxonomy="category" post_type="post" text="Blog PDF"]
If you change category=”full” to category =”2″ (assuming 2 is the post category you want) then you can export the category with id 2.
This is not clear at all. I just want to have a shortcode where I can export the post as PDF.
