CUPS encryption. #175

Closed thegala closed 4 years ago

thegala commented 4 years ago

When selecting any Android Cups printer i got error.

This printer isn't available right now.

When looking logs on my server i found:

[Client 968] Unable to encrypt connection: A TLS fatal alert has been received.

Does this application enables encryption when talking to CUPS server? Is there anyway to enable it?

It is enabled by default and mandatory on most Android versions. If you use avahi/zeroconf/bonjour you should ensure the advertised address is the secure one. Otherwise you could disable the non-secure interface in cups or set up a redirection.

I hope this helps. I'm closing as not an issue but remain available for comment of course!
