I am on Kubuntu 17.10 and I am suffering this bug. I do not have the web interface enabled but I have an IPP printer. I have attached the cupsd.conf on my system. I think this is the relevant part of the file:
# Only listen for connections from the local machine. Listen localhost:631 Listen /var/run/cups/cups.sock # Show shared printers on the local network.
