At best the previous explanation for closing this bug is unhelpful and at worst rubbish. Here we go again:
Relevant documentation is at http://localhost:631/help/network.html and http://localhost:631/help/api-httpipp.html The cupsd.conf has SSLListen 0.0.0.0:631 which implies only an SSL request will establish a connection. "Encryption IfRequested" and "Encryption Required" both make an initial unencrypted connection which can then be switched to TLS after it is established. The server is set up to reject such connections, making "Always" the only workable option.
