CHAPTER 1 INTRODUCTION TO THE ZEBRA
SCANNER WMI DRIVER
Overview
Windows Management Instrumentation (WMI) is a free component of the Microsoft Windows® operating
system that provides a scalable system management infrastructure. Using a free provider plug-in from Zebra,
WMI enables local and network remote management of a scanner. System administrators can leverage WMI to
query and set information on desktop systems, applications, networks, components, and accessories, such as
a scanner. Developers can use the underlying WMI Application Programmers Interfaces (APIs) to create
system management applications/tools that organize system information for the purposes of asset
management or other enterprise level activities. The WMI API supports the use of several high level languages
such as C++, C#, VB, VBScript, and Jscript.
For more information, search for WMI on http://msdn.microsoft.com

Zebra Scanner WMI Driver Architecture
Managed Objects and Providers
A provider is a COM object that monitors one or more managed objects for WMI. Similar to a driver, a provider
supplies WMI with data from a managed object. A provider also handles messages from WMI to the managed
object.
A managed object is a logical or physical enterprise component, such as a hard drive, network adapter,
database system, operating system, process, or service. A managed object communicates with WMI through a
WMI provider that calls methods in the COM API for WMI.
For example, the Platform SDK ships with the Registry provider, which accesses data in the system registry.
WMI passes information from the providers to the WMI infrastructure when client applications and scripts
request registry data. The Registry provider has one WMI class, StdRegProv, with many methods but no
properties. Other providers, such as the Win32 provider, usually have classes with many properties but few
methods, such as Win32_Process or Win32_LogicalDisk.
INTRODUCTION TO THE ZEBRA SCANNER WMI DRIVER1 - 3
WMI Infrastructure
The WMI infrastructure is a Microsoft Windows operating system component comprised of two components:
the Windows Management service, including the WMI Core, and the WMI repository. The Windows
Management service acts as an intermediary between the providers, management applications, and the WMI
repository. The repository contains only static data about objects, such as the classes defined by providers.
WMI obtains most data dynamically from the provider when a client requests it.
Most provider classes, such as Win32_LogicalDisk, are defined in Managed Object Format (MOF) files, are
then compiled into the WMI repository by mofcomp.exe. A provider also has a DLL file which contains the code
that implements the classes.
WMI Management Applications and Scripts
A management application or script is an application that interacts with the WMI infrastructure. A management
application can query or enumerate management data by calling either the COM API for WMI or the Scripting
API for WMI. Management applications can call methods in either API to send instructions or reconfigure a
managed object. The only data or actions available for a managed object such as a disk drive or a service are
those that a provider supplies.
Zebra WMI Provider Plug-in
Zebra's driver provides a WMI interface with a mechanism to view and program scanner settings. It also
enables an administrator to perform actions such as firmware updates, event reporting on the progress of a
firmware update and the discovery of scanners, as defined in the Symbol Scanner Managed Object Format
(MOF) file. By leveraging the WMI infrastructure built into the Windows Operating System, an application
developer can write a management application to perform the following enterprise level activities:
•
Discovery (asset management)
•
Configuration deployment
•
In system firmware update.
Supported Devices
•
Any RSM-ready Zebra scanner
•
Supported Scanner Communication Modes
•
IBM Hand-held USB.
System Requirements
For system requirements, refer to the Scanner SDK Developer’s Guide.

CHAPTER 2 INSTALLATION
INSTRUCTIONS
Overview
The Zebra WMI providers are installed as part of the Zebra Scanner SDK Installshield® package. There are
two WMI providers: Scanner WMI provider; and, Driver WMI provider. Two Windows services (Symbol Scanner
Management and RSM Driver Provider Service) are installed and start automatically. These two services are
called Zebra's WMI provider, also called the WMI plug-in.
For general installation instructions to install the Zebra Scanner SDK, refer to the installation instructions in the
Zebra Scanner SDK Programmer's Guide.
NOTE The Zebra CoreScanner Driver is a prerequisite for the Zebra WMI provider. The Zebra Scanner SDK
Installshield® package automatically installs the CoreScanner Driver if it is not already on the system. A
complete installation of the SDK installs the Zebra WMI provider. If you select the custom installation, you
must select the Scanner WMI provider and Driver WMI provider components.
2 - 2 WMI DRIVER DEVELOPER’S GUIDE
Basic Installation Verification
You can perform a basic inspection on your system process list to verify a successful installation of the Zebra
WMI provider.
To do a simple check of the Zebra WMI provider's operation:
1.Right click on the Windows Task Bar and select Task Manager.
Figure 2-1
2.Select the Processes tab.

ANSI Terminal. A display terminal that follows commands in the ANSI standard terminal language. For example, it uses
escape sequences to control the cursor, clear the screen and set colors. Communications programs support the
ANSI terminal mode and often default to this terminal emulation for dial-up connections to online services.
ASCII. American Standard Code for Information Interchange. A 7 bit-plus-parity code representing 128 letters,
numerals, punctuation marks and control characters. It is a standard data transmission code in the U.S.
Autodiscrimination. The ability of an interface controller to determine the code type of a scanned bar code. After this
determination is made, the information content is decoded.
B
Bar. The dark element in a printed bar code symbol.
Bar Code. A pattern of variable-width bars and spaces which represents numeric or alphanumeric data in
machine-readable form. The general format of a bar code symbol consists of a leading margin, start character, data
or message character, check character (if any), stop character, and trailing margin. Within this framework, each
recognizable symbology uses its own unique format. See Symbology.
Bar Code Density. The number of characters represented per unit of measurement (e.g., characters per inch).
Bar Height. The dimension of a bar measured perpendicular to the bar width.
Glossary - 2WMI DRIVER DEVELOPER’S GUIDE
Bar Width. Thickness of a bar measured from the edge closest to the symbol start character to the trailing edge of the
same bar.
BIOS. Basic Input Output System. A collection of ROM-based code with a standard API used to interface with standard
PC hardware.
Bit. Binary digit. One bit is the basic unit of binary information. Generally, eight consecutive bits compose one byte of
data. The pattern of 0 and 1 values within the byte determines its meaning.
Bits per Second (bps). Bits transmitted or received.
Bit. Binary digit. One bit is the basic unit of binary information. Generally, eight consecutive bits compose one byte of
data. The pattern of 0 and 1 values within the byte determines its meaning.
bps. See Bits Per Second.
Byte. On an addressable boundary, eight adjacent binary digits (0 and 1) combined in a pattern to represent a specific
character or numeric value. Bits are numbered from the right, 0 through 7, with bit 0 the low-order bit. One byte in
memory is used to store one ASCII character.
BOOTP. A protocol for remote booting of diskless devices. Assigns an IP address to a machine and may specify a boot
file. The client sends a bootp request as a broadcast to the bootp server port (67) and the bootp server responds
using the bootp client port (68). The bootp server must have a table of all devices, associated MAC addresses and
IP addresses.
boot or boot-up. The process a computer goes through when it starts. During boot-up, the computer can run
self-diagnostic tests and configure hardware and software.
