HP Web Jetadmin
A web-based fleet management software tool for remote installation,
configuration, problem resolution, proactive management, and reporting. For

IP multicast
A one-to-many transmission of data over an IP network.
IPSec
Internet Protocol Security (IPsec) is a suite of protocols for securing Internet
Protocol (IP) communications by authenticating and encrypting each IP packet of a
data stream. IPsec also includes protocols for establishing mutual authentication
between agents at the beginning of the session and negotiation of cryptographic
keys to be used during the session.
In our case, IPsec is used to protect data flows between the host and the printer.
Job Held Timeout
(LJ feature)
This feature is part of the Job Retention feature. It limits a held job to the selected
time, and then the printer deletes it. You should select a reasonable timeout value
for this setting to allow enough time for a user to walk to the printer to print a job
or to allow time for jobs to print in a queue.
Job Retention
(LJ feature)
This feature provides job retention options such as private job and hold job. You
will be able to ensure that they are present during printing to provide privacy for
documents in the printer output bins.
Multicast DNS (mDNS)
Also known as Bonjour or Rendezvous, mDNS uses IP multicast with DNS to
provide the capabilities of a DNS server for service discovery in a small network
that does not have a DNS server.
NTLM
NTLM is a suite of authentication and session security protocols used in various
Microsoft network protocol implementations. There are two types of
authentications named NTLMv1 and NTLMv2, version 2 improves security
authenticaion over version 1.
PJL Password
(LJ feature)
The PJL password feature helps to protect the printer from unauthorized
configuration changes through Print Job Language (PJL) commands. It does not
affect ordinary print jobs. Once the PJL password is configured, the MFP requires it
before it will process any of these commands
Remote Firmware Upgrade
(LJ feature)
This service allows an administrator to use a custom application to upgrade the
printer’s firmware remotely. Since HP recommends using HP Web Jetadmin to
upgrade MFP firmware, you should disable Remote Firmware Upgrade.
Simple Network Management
Protocol (SNMP)
This is a network monitoring and control protocol.
SNMPv3
SNMP (Simple Network Management protocol) allows users to manage the printer
by using SNMP management tools, such as HP Web JetAdmin. SNMP is also the
protocol for communicating from the printer to the Windows driver. SNMPv3
provides security through user authentication and data encryption
Subnet
A logical division of a local area network, which is created to improve performance
and provide security. A subnet limits the number of nodes that compete for
bandwidth.
