SAP R/3 Device Type Briefing Paper

HP Web Jetadmin
Briefing Paper
Keeping a diverse range of printers, copiers and
multifunction products (MFPs) running at optimal
performance can be a challenge for IT managers and
network administrators. Organisations often have devices
from a number of manufacturers. Each manufacturer
offers proprietary device management tools but these
cannot be used to manage other manufacturers’ devices.
Instead of using several tools, IT managers and
administrators prefer to use one system for managing all
their devices.
HP Web Jetadmin benefits include:
Hewlett-Packard (HP) addresses this need by offering
non-proprietary device management software called
HP Web Jetadmin. Unlike proprietary device management
tools, HP Web Jetadmin can be used to monitor many
different models from various manufacturers. HP Web
Jetadmin is widely accepted and used by IT managers. By
ensuring that our devices adequately support HP Web
Jetadmin, Ricoh can maximise IT sales.
All devices can be easily managed through a single
web-based software solution
Administrators can proactively solve problems before
they affect productivity, saving time and money
Functionality can be expanded with optional plug-ins,
for example, report generation
Security features including SSL, SNMP version 3.0
and authentication are available.
What is HP Web Jetadmin?
HP Web Jetadmin is non-proprietary software for
installing, configuring and managing networked devices
including printers, scanners and MFPs. It allows network
administrators to use a single software interface to
manage devices from all major manufacturers.
How HP Web Jetadmin works
Any device that supports standard printer MIB (RFC 1759)
and MIB II (RFC 1213) can be monitored using HP Web
Jetadmin, provided that the print server can send printer
MIB requests to the printer and relay answers back to HP
Web Jetadmin.
HP Web Jetadmin is free and can be downloaded from HP
websites. HP Web Jetadmin is accessed via a standard
web browser and enables administrators to remotely
manage networked devices.
However, each manufacturer has its own proprietary MIBs
that define a device’s advanced capabilities. To enable HP
Web Jetadmin to communicate effectively with another
manufacturer’s proprietary MIB, a device plug-in is
required. Some manufacturers have developed device
plug-ins via HP’s third party device certification program.
HP Web Jetadmin can send email messages, or alerts,
whenever a device requires intervention. For example, an
administrator can receive an email when a device runs out
of paper or has low toner levels. Receiving early
notification of printer events allows administrators to
correct the problems before they impact end user
productivity, saving time for both the administrator and
the end user. Users can also perform certain tasks using
HP Web Jetadmin. For example, they can monitor device
status and search for a device by location or capabilities.
HP Web Jetadmin can monitor devices from
all major manufacturers from a single interface
Support for non-HP devices
Ricoh provides a plug-in
There are three levels of support for non-HP devices:
Ricoh has partnered with HP to develop a plug-in for HP
Web Jetadmin. The plug-in makes advanced functionality
available with Ricoh models. This enables customers who
are already using HP Web Jetadmin to effectively manage
Ricoh devices.
Limited functionality—via standard printer MIB and
Additional functionality—when a manufacturer’s
plug-in for a specific device is installed, some additional
functionality will be available for most of the
manufacturer’s models
Advanced functionality with full graphical support—
when a manufacturer’s plug-in for a specific device is
The Ricoh plug-in, which is provided at no charge, has
been certified by HP, and can be downloaded from Ricoh
and HP websites.
When HP Web Jetadmin communicates with a device via the
standard printer MIB and MIB II, only limited functionality is
supported. For example, while some errors can be monitored,
toner levels, paper levels and alerts are not supported.
Without a specific device plug-in, a device is represented by
generic graphics.
Supported features
When the Ricoh plug-in is installed, the following HP Web
Jetadmin functions are enabled for supported models:
Device discovery—automatically detect
pre-configured, DHCP enabled and IPX configured
Device groups—organise devices into groups by
floor, department or network segment
Device configuration—remotely configure Ricoh
devices individually or by group
Device capabilities—identify installed accessories
and their capabilities, including RAM, HDD, print and
scan speeds
Generic graphics—without a plug-in
Real-time device status—detect and view status
including paper levels, toner levels
When a specific device plug-in is installed, more advanced
functionality is supported. For example, HP Web Jetadmin can
provide a graphical representation of that device. With a
specific device plug-in installed, the graphic accurately
represents that device’s accessories and finishing capabilities.
This means that when an error occurs, it is reflected in the
device graphic, allowing the device to be monitored ‘at a
Device statistics—export counter and network
communications statistics in CSV or XML file format
Diagnostic information—view diagnostic
information about devices on the network
Problem alerts—receive alerts via email when a
device requires intervention or service, such as low
toner or out of paper
Device embedded web server—access any Ricoh
device’s embedded web server and enable additional
alert types, for example, drum, fuser, transfer kit and
toner levels.
Alert types
The alert types supported by the Ricoh plug-in include:
Graphical representation—with a plug-in
Installing a specific device plug-in makes more functionality
available for other models produced by the same
manufacturer. Although full graphical representation of the
device and some alert capabilities are not available, the
available functionality is greater than when no plug-in is

Out of paper
Manual feed required
Toner low
Out of toner
Intervention needed
Output bin full
Printer error
Paper jam
Stapler error.
Competitor offerings
In general, non-HP models do not support the above functions
to the same degree as HP devices. For example, when
configuring HP devices, an administrator can set default paper
sizes and paper types, or specify whether the device should
continue printing when the toner is low. A non-HP device
offers a simpler set of device configuration features.
As standard, HP Web Jetadmin provides device plug-ins for
the following manufacturers:
There are also some additional functions that are only
available for HP devices. For example:
These plug-ins only provide general support, for example,
basic capabilities and status.
Print queue creation
For additional functionality, and graphic representation, a
specific plug-in developed by that manufacturer is required.
The following competitors have developed their own device
Firmware upgrades
Device discovery looks for HP’s default IP address,, so it does not work for non-HP devices that
do not have an IP address set.
Some earlier HP models did not support standard printer MIB,
so they do not support all HP Web Jetadmin’s
advanced features.
