Looks like a FAQ site, try https://www.phpmyfaq.de/
On second thought, I think it's fake Wordpress site with titles and contents that look like a Q&A site or FAQ site.
You can create a new Q2A site but do not use the Q&A structured data markups. You are the only asker, nobody can answer. Question titles contain questions, question bodies contain answers. Remove unnecessary things to display (answer button, flag, avatar, time....).
To generate PDF files, you need something else, better look for open source libraries.
