You need to ensure that Configuration Manager data includes information about the printers

Your network contains a System Center 2012 Configuration Manager environment.
Your company deploys 1,000 client computers.
You discover that information about printers fails to appear in any inventory queries or
reports. Information about other hardware devices appears in the inventory queries and
reports.
You need to ensure that Configuration Manager data includes information about the
printers.

A.
Add a WMI class to the Hardware inventory Classes list.

B.

C.

E.
Add a file name to Software Metering.

F.
Select Collect NOIDMIF files in Hardware Inventory.

G.

Explanation:
Hardware Inventory Class
All objects in AD are instances of classes defined in the AD schema. The schema provides
definitions for common objects such as users, computers, and printers
Adding new device/class to hardware inventory
In the hardware inventory class window click the add button
Next click the ‘Connect’ button

Select the desired class and click ‘Edit’

Give your new device/class a friendly name (instead of the default class name)

Now you can select the properties you want to add (as you did in the previous section).

You can see the result in the resource explorer:

Hardware inventory works by querying Windows Management Instrumentation (WMI) for all
data from certain WMI classes. WMI includes classes for operating system configuration and
entities (such as user accounts), installed software, software configuration, and other objects
(such as for the logged on user). These classes are supplements to hardware classes.
Hardware inventory collects information about many things besides hardware. For example,
it can inventory software by collecting details about programs listed in Add or
Remove Programs in Control Panel or programs that have been installed using Windows
Installer.

Most of your inventory needs can be served by hardware inventory collection alone.
