My suggested work around above does not fix the issue (completely) because systemd is in charge of the socket - so as well as commenting out "Listen /run/cups/cups.sock" in /etc/cups/cupsd.conf you have to also do the following:
systemctl stop cups.service systemctl stop cups.socket rm /run/cups/cups.sock systemctl disable cups.socket systemctl start cups.service
