If you're using 'secure' as 'confidential', then the client requests
that protection by making the connection on the SSL port (https:),
and indicates that it does not require confidentiality by making the
request on a non-SSL port.
The service (the printer or print server) probably cares more about
authentication than confidentiality for IPP, and it can get that on
a connection that is either confidentiality protected or not using
Digest Access Authentication.
