I am experiencing the exact same symptoms since about three weeks.
Uninstalling and reinstalling does not help:
sudo dpkg -P cups-pdf sudo apt-get install cups-pdf
It says: Setting up cups-pdf (2.6.1-9)
but when I print, no matter from what application, the result is an empty 2.2KiB file ~/PDF/PDF.pdf
/etc/cups/ppd/PDF.ppd does not exist on the system, the only file in /etc/cups/ppd is the one for my physical printer
