On a recently upgraded Ubuntu 16.04 system, I get the following message
when starting xsane for the first time after opening a session:

HPLIP cannot detect printers in your network. This may be due to
existing firewall settings blocking the required ports.
When you are in a trusted network environment, you may open the ports
for network services like mdns and slp in the firewall. For detailed
steps follow the link.

I have two local HP USB printers (without scanner functionality) and one
local non-HP USB scanner. The local scanner is shared on the network
through the saned net backend. Everything is working properly except
that error message that pops up when starting xsane.

How can I get rid of that message without opening ports? Is there a way
to prevent xsane from using HPLIP network discovery?
