PDF's can be created with Tableau Online with the addition of the ".pdf" in place on the url per - http://onlinehelp.tableau.com/current/pro/desktop/en-us/help.html#link_view.html
Is this process not working as desired?
Diogo Braga you can automate pdf printing with help of tabcmd and python script .
I tried the approach and it's working fine for me .
Currently we are printing around 300 pdf from a single dashboard with 3 filters(iterative filtering) the script will take around 2 to 3 hours to generate all pdfs in their respective folders.
we are doing this with tableau server.
