OVERVIEW
Administrators want the ability to effectively discover and manage printers offered by all major printer
vendors from a single software interface. Only having to install one software and learn a single
interface saves valuable time and money. The tool also has to provide adequate levels of support for
all vendors. Fortunately, HP Web Jetadmin is a premier printer management solution that can
effectively discover and manage non-HP printers. The level of support provided depends on the ability
of the device to adhere to a set of industry standards.

DISCOVERING DEVICES
During discovery of devices, HP Web Jetadmin uses SNMP queries to gather information from the
device. If HP Web Jetadmin concludes that the device is a peripheral such as a printer, plotter, or
multifunction device, it will display it in the list of discovered devices. In order for HP Web Jetadmin to
conclude that a device is a peripheral, the device must be able to answer a set of industry-standard
questions.
A Management Information Base (MIB) is a set of objects that defines the types of SNMP queries that
can be asked of a device. For example, the Standard Printer MIB (RFC 1759) is a generic set of
objects to which most peripherals should be able to provide answers when queried. The Standard
Printer MIB consists of objects that describe functionality and capabilities of the printer such as page
counts or media types. Other common MIBs include MIB2 (RFC 1213) and the Host Resources MIB
(RFC 1514). Device vendors also have a set of proprietary MIBs that contain information unique to
their devices. HP Web Jetadmin must have knowledge of MIB objects in device plug-ins before it can
send queries to devices using those MIB objects.
Devices must be able to answer queries defined in the common industry-standard MIBs in order for
HP Web Jetadmin to discover the devices. Otherwise, there is not enough information pertaining to
the device to warrant displaying it in the list of discovered devices. HP Web Jetadmin focuses on
printer management, and it would be increasingly difficult to distinguish devices as printers unless
they can answer a standard set
of questions such as those
defined in the Standard Printer
MIB.
Once a device is discovered in
HP Web Jetadmin, the level of
support that can be provided will
depend on the depth of queries
defined in the respective device
plug-ins.

DEVICE PLUG-INS
Device plug-ins in HP Web
Jetadmin contain SNMP queries
to support functionality for a
device. The more definitions that
exist in the plug-in that are
unique to that device, the higher
the level of support that is
provided.
HP Web Jetadmin has no
specific knowledge of

Figure 1—Third-party device support

proprietary objects for a third-party device, therefore a single plug-in containing industry-standard
objects is used for each vendor. The level of information that can be provided depends on the ability
of the device to answer the standard queries.
For HP devices, a device plug-in exists for every HP model that contains proprietary objects to provide
advanced support.

LEVEL OF SUPPORT
Third-party device support in HP Web Jetadmin can be quite extensive—however, it is strictly the
responsibility of the device to answer the standard queries. A significant amount of HP Web Jetadmin
functionality can be supported through standard queries such as basic status, configuration, alerts,
reporting, and page counting. HP Web Jetadmin attempts to support the following functionality for
third-party devices using standard queries for basic support:


RESERVED FUNCTIONALITY
While a majority of functionality in HP Web Jetadmin is provided by using SNMP queries, some
functionality is reserved for HP devices only, as the functionality requires techniques beyond querying
SNMP objects. The basic and advanced support provided for non-HP devices is restricted to the
usage of industry-standard or vendor-specific SNMP queries to gather information. Functionality that is
reserved for HP devices due to non-SNMP techniques to provide it includes:


Firmware upgrades



Print queue creation



Some extended configuration items



Print Test Page button



Secure disk erase



Font and forms management

FUNCTIONALITY DEFINITIONS
The following section provides definitions for many of the supported features for third-party devices
and the objects used for obtaining the information. The feature is supported if the device can answer
the industry-standard query defined in these definitions.
Bitmap and Icon
HP Web Jetadmin displays any predefined bitmaps and icons that have been created in a device
plug-in. HP devices have a unique matching picture, while third-party support provides one generic
picture per third-party vendor.
Model
The printer model name appears according to the response to hrDeviceDescr.
Status
Device status, indicating the current state of the printer (for example: Online, Paper jam) is displayed
based on responses to standard objects such as hrPrinterDetectedErrorState.
Control Panel Display
The current message on the printer front panel is displayed using prtConsoleDisplayBufferText.
Serial Number
The Serial Number is a unique manufacturing identifier for the printer. The serial number is a critical
identifier item for HP Web Jetadmin that is used to determine the uniqueness of a device along with
other items such as MAC Address and IP Address. Some functionality, such as Reports, is blocked in
HP Web Jetadmin if the serial number cannot be obtained. Therefore, HP Web Jetadmin makes
strong efforts to obtain the serial number from third-party devices. The most typical and widely
supported object for obtaining serial number is prtGeneralSerialNumber.
Engine Cycle Count
Engine Cycle Count is a value stored on the printer that represents a cumulative total of pages printed
for the life of the printer. Engine Cycle Count is displayed if a printer supports prtMarkerLifeCount.
Page counts for monochrome, color, simplex, duplex, fax, copy, and scan are only obtainable via
proprietary queries and only supplied for HP devices.
IP Hostname
IP Hostname is displayed as long as the operating system can resolve an IP address to a hostname
from a name server such as DNS or WINS using a GetHostByAddr call. System Name, which can be
5

the hostname if the NIC registers it with a name server, is displayed if the device answers the
sysName MIB2 object.
System Contact
System contact is displayed according to the response to sysContact.
Description
Description is displayed according to the response to sysLocation.
Storage
Presence of storage media such as hard disk, flash disk, RAM disk, and installed RAM can be
detected using hrDiskStorage objects. Additional storage information is provided under the Storage
tab for certified devices.
Capabilities
Capabilities such as installed languages, trays, and accessories are displayed on the Capabilities
and Detailed Info tabs using Status page as supported by the device and based on objects such as
prtInterpreterDescription or prtInputDescription.
Remaining Toner Levels
The approximate amount of toner or ink remaining in the cartridge cavity is determined by calculating
a percentage based on the prtMarkerSuppliesLevel and prtMarkerSuppliesMaxCapacity.
Remaining Input Tray Levels
The approximate amount of paper remaining in a particular tray is displayed by calculating a
percentage based on responses to the Standard MIB objects prtInputCurrentLevel and
prtInputMaxCapacity.
Alerts
Polling at a specified interval is used to provide alerts based on status queries that match certain
conditions or prtAlerts table objects. Standard status queries can typically determine the following
types of alert conditions:


Toner Out



Toner Low



Paper Out



Paper Low



Cover Open



Offline



Paper Jam
Printer Error

HP devices can process traps for real-time alerts when events occur for most items under General
category. Polling of remaining supplies levels to provide Supplies alerts at desired thresholds is also
available for HP devices.
Configuration
The following items are provided at minimum for configuration, assuming the device supports the
objects:


System Contact (sysContact)



System Location (sysLocation)



Control Panel Language (prtConsoleLocalization)
6



Contact Person (prtGeneralServicePerson)



System Name (sysName)

HP devices can provide extended configuration items using proprietary objects.
Reports
Third-party support includes only reports that indicate Device Inventory or Engine Cycle Counts. HP
devices include reports that make use of the various supported page count values such as Accessories
Inventory (capabilities), Supplies Utilization (marker supply info), Device Utilization (page counters),
and Peak Usage (hourly page counters).

TROUBLESHOOTING
Trying to determine why a particular third-party device supports what it does usually boils down to the
ability of the device to answer the queries HP Web Jetadmin sends. HP Web Jetadmin is at the mercy
of the device to answer industry-standard queries. Some devices support more gauges than others
and it cannot be assumed that all devices from a particular vendor will support the same features. For
example, one Xerox model may support the control panel display while another Xerox model does
not. Common explanations for why particular items may not appear for devices include:
Issue: A gauge may be present for a
consumable but the gauge is hashed out
instead of containing a remaining
percentage.
Reason: If a device answers
prtMarkerSuppliesDescription correctly,
the gauge is present, since HP Web
Jetadmin knows the consumable exists.
However, if the device cannot answer
either prtMarkerSuppliesMaxCapacity or
prtMarkerSuppliesLevel correctly, the
percentage cannot be calculated and
HP Web Jetadmin displays hashes
instead to indicate an “unknown” level.

Figure 4—Supplies gauges contain hashes instead of levels. Generic HP
bitmap

Issue: A paper tray gauge does not
indicate a remaining percentage.
Reason: If a device answers the
prtInputType query to indicate a tray is
present, the device may respond to the
prtInputMaxCapacity and
prtInputCurrentLevel queries with either
valid values or indicate that at least one
sheet remains. If valid values are
Figure 5—Device utilization report displays only total pages
returned, a calculation is presented. If
valid values are not provided, HP Web
Jetadmin displays either “empty” or “not empty” depending on whether the device indicates at least
one sheet remains.
Issue: Control Panel displays “Not Supported” or “Unknown”.
Reason: “Not Supported” indicates the device did not respond to the prtConsoleDisplayBufferText
object. “Unknown” may indicate that the device recognizes the prtConsoleDisplayBufferText object
but did not respond with any text.
7

Issue: The model name for the
device appears to be much
longer than the true name of the
device.
Reason: HP Web Jetadmin relies
on hrDeviceDescr to display the
model name. Properly truncated
Figure 6—Unknown front panel message. Non-truncated device model name.
model names are generally
provided in proprietary objects.
HP Web Jetadmin does not know how to truncate a response to hrDeveiceDescr if it contains too
many characters. For example, if a Lexmark printer responds with “Lexmark X652de 7932M8R
LJ.MN.P092”, HP Web Jetadmin cannot know where to truncate the string.
Issue: No consumable gauges
are present for items such as
toner or fuser.
Reason: A device must answer
prtMarkerSuppliesDescription
correctly, otherwise HP Web
Jetadmin has no idea the
consumable exists and cannot
display a gauge.

SUMMARY
By supporting third-party printers in HP Web Jetadmin, LAN administrators can now discover and
manage printers from all major printer vendors with a single software interface. By simplifying printer
management with a single, powerful tool, HP Web Jetadmin can save administrators significant time
and effort.

The following table contains a list of potential functionality that HP Web Jetadmin supports for
third-party devices. An asterisk (*) next to a consumable gauge indicates the gauge is present, but the
device is unable to reflect an exact value. In the case of Paper Trays, since it can reflect a value of
“Empty” or “Not Empty”, it is considered a “Y” (yes) for support. In the case of the other consumable
gauges, since it reflects no value at all, it is considered an “N” (no) for support.
