I am running MS Office under wine and would like to print PDF documents.
Installing the official extension via wine does nothing.
The answer is cups-pdf
sudo apt-get install cups-pdf
or from Ubuntu 16.04 on
sudo apt-get install printer-driver-cups-pdf
If there's no such folder, create PDF at your home:
Now you're set to go. From MS Word, do Print -> Select PDF as printer -> wait for the printing to complete (it takes some time).
