At this moment Adobe Captivate is listed under Print and Publishng. However Captivate results in a special kind of website, has no printing functionality. It is not at all related with Framemaker nor InDesign. Many users also refer to it as a tool to create videos. It is related much more with Animate CC, Web tools like Dreamweaver and Muse, After Effects, Premiere Pro and even Audtion. Not at all with Printing. Same is valid for Adobe Prime, a Learning Management system, no link whatsoever with Print.
It makes it very difficult for newbies to find the Captivate forum.
