I have heard of some devices using loopback IPs (127.x.x.x) to do
something (not sure if printing or scanning). And I have also heard of
firewalls sometimes blocking loopback IPs. Why anyone would block a
loopback IP (which can go nowhere outside your own PC) is beyond me.

Have you tried disabling NAV before installing the HP software? I have
also had some trouble with unrecognized Java class installing some HP
OfficeJet software. Although, it somehow still installed after a very
long delay.
