What if what's being added is a remote printer, that's merely a way to smuggle documents out of a company? So direct attach printers are probably fair game for adding without authentication. The user clearly has physical access to both computer and printer, the most applicable security control in this context is physical. But to add a non-local IPP printer is possibly a red flag. Curiously enough, I was thinking exactly the opposite - anyone able to open a TCP/IP socket is able to print on a remote printer, so this does not need to be restricted; but accessing local hardware may be something a system administrator of a multi-user system may want to restrict. (You may have noticed that at least in some Windows versions, network printers can be configured per-user, but hardware-attached printers are always system-wide.) A complete lockdown to prevent transferring data out of the system is a much harder problem (even if you only allow users to run a web browser, they may use it to send data to a server).
