No authenticated printing support #106

Under the CUPS html settings I set Operation Policy: Authenticated, and this driver no longer works, with error message: "Couldn't handle job"

It would have to query for a user-name and password somehow.

Do you have a pcap or a log that would help me understand what's going on?

I see. You need to change the printer URL to use https. Or change the mDNS/whatever configuration to advertise the https URL over the http one.

Did you manage to fix this?

This doesn't provide enough information, HTTP basic auth is supported and the error seems to be about the wrong use of plain HTTP. Please reopen if you have more details to share.
