AFAIK, there's only one protocol in the list above (IPP). http(s) is a
transport binding. ipps is a "URI scheme, which is used to designate the
access to the network location of a secure IPP print service or a
network resource managed by such a service."

 cupsctl --share-printers
(same subnet)

 lpadmin -p <name of shared printer> -o printer-is-shared=true

https://www.cups.org/doc/sharing.html

I didn't do it that way that, though. I turned on sharing via the web
interface and without further ado the printer shared itself on the LAN.
Can't imagine what your difficulty might be (unless your not in
administrative mode or something).
