The remote system is running an NFS server which is configured
in such a way that it allows unauthenticated users to manipulate
the file system using unverified credentials. This can be
accomplished by spoofing the user ID (UID) and group ID (GID)
values in NFS RPC call packets.
Impact:
An unauthenticated network-based attacker can leverage this
misconfiguration issue to access and modify sensitive files that
are present on the remote system with super user privileges. This
level of access typically results in a complete compromise of the
vulnerable system.
Solution: If the NFS service is not necessary or is not being used, disable
the service. Alternatively, if the service is relied on, the issue may
be resolved either by implementing an authentication scheme

Easiest would be to disable NFS server (telnet to IP of JetDirect, type 'help', and look for disabling NFS printing)

Some non-standard HP protocol. Probably you upload text files and images and printer prints them...
