I've compiled all of the Qlik Sense API Documentation on the Qlik website into a MS Word document which is easily searchable and printable (though it is 400+ pages). It was last updated May 24th, 2016 and Qlik Sense version 2.2.
URL to version 2.2: APIs & SDKs ‒ Qlik Sense
URL to version 3.2: APIs & SDKs - Qlik Sense
If there is interest for it, I will take the time to reduce the page count so that it can be printed with less environmental impact. Additionally, a table of contents can be added so that it can be navigated more easily.
