Can I handout versions of multiple PowerPoint decks converted to PDF files? Using PowerPoint 16.15 on Mac OS X High Sierra 10.13.15...
I have a folder of PPT files.  I would like to save them as PDF files, the layout being Handouts (6 per page) and the output being black and white.
Is there some way (e.g., using Automator, scripting or automation) to do this for every file in the folder?
It took me a few hours to come up with a solution that works in my environment.
Please note that some elements need internationalization like &quot;Vorschau&quot; or &quot;Sichern&quot;. This is a german solution working with PowerPoint for Mac 16.16.27 on macOS HighSierra 10.13.6.
I had to heavily debug things with ScriptDebug ($99 well spent ..) to get things working. Please note how Preview is used for the actual PDF saving. I tried doing this from Powerpoint but it was unreliable.

see https://github.com/WolfgangFahl/ppt2pdf for a maintained version of this.
Example call
ppt2pdf *.pptx

Please note that the files are expected in the current directory. The applescript ppt2pdf.scpt expects the path to the files as the first parameter and all others as just filenames. This behavior could easily be changed.
