First suggestion: it's a commercial product. Why not open a support ticket
with them?

Second: I'd log into the printer, and check a number of things: first,
does it have bonjour enabled? Does it have "network printing" enabled? And
are its cert, the CA, and the *other* cert all valid? The last, which
sometimes you can only find under networking, not under security, there
may be an option to regenerate a new self-signed cert.
Why it doesn't like C6, which I am assuming is fully updated, is a
question for their support, if the o/p from the package doesn't tell you.
