I'm not telling you any such thing. I'm merely saying that for it to
support IPP, it has to be able to refuse attempts to perform IPP
operations that are not authenticated.
If whoever makes your printer sees fit to build the printer so that
it loads its username/passwords from DHCP, along with the other IP
stuff, that's fine. Heck, for a soho printer I would probably
consider it acceptable for the printer to accept a single
username/password (unique to that printer), which was burned in
firmware, and printed on a label on the inside of the printer.
That will at least prevent attacks, and people who want to support
large numbers of users at their soho printer can just spool through
a proxy that knows the password.
And though it would be really silly to hook a printer up to the Internet
that allowed so much potential for abuse we're only insisting that it
be possible for IPP to be authenticated.
(though I would strongly recommend that while you're at it, you provide
the ability to require authentication for *all* of b-e above. Face it,
if you leave the door wide open, sooner or later your products
will be subject to attack. It doesn't cost much to protect your
customers now.)
