The attacker can be on the LAN though.

Sure but security isn’t about being 100% protected which is impossible, but lowering your attack foot print. Unless you have a ton of people hooking to your LAN regularly then this still greatly lowers you chances of getting hit with this particular security flaw by people on the WAN

A useful target might be university networks, although IIRC our university printers weren’t available for discovery. Instead we would send our documents to a special email that would forward it to a local print server so we could get charged for it.
