NETWORK PRINTER INVENTORY IN SYSTEM CENTRE CONFIGURATION MANAGER (SCCM 2012).

Question

SCCM HW inventory agent runs as the ‘SYSTEM’ and cannot see the end-users network drives and printers. The following two step process will help circumvent the above stated limitation.
1) CREATE HKEY_LOCAL_MACHINE\SOFTWARE\SCCMINVENTORY\NETWORKPRINTERS PATH IN THE REGISTRY.
Create a SCCM package.
The package should run as administrator.
The package should run whether or not a user is logged on.
POWERSHELL PACKAGE 1 (Prerequisite):
if (!(Test-Path HKLM:\SOFTWARE\SCCMINVENTORY)) {new-item HKLM:\SOFTWARE\SCCMINVENTORY -ErrorAction SilentlyContinue}
$perm = get-acl HKLM:\SOFTWARE\SCCMINVENTORY -ErrorAction SilentlyContinue
$rule = New-Object System.Security.AccessControl.RegistryAccessRule("Authenticated Users","FullControl", "ContainerInherit, ObjectInherit", "InheritOnly", "Allow") -ErrorAction SilentlyContinue
$perm.SetAccessRule($rule)
Set-Acl -Path HKLM:\SOFTWARE\SCCMINVENTORY $perm -ErrorAction SilentlyContinue
if (!(Test-Path HKLM:\SOFTWARE\SCCMINVENTORY\NETWORKPRINTERS)) {new-item HKLM:\SOFTWARE\SCCMINVENTORY\NETWORKPRINTERS -ErrorAction SilentlyContinue}
SAVE POWERSHELL FILE AS: PrinterInvRegSetup.ps1
SETUP THE SCCM PACKAGE/PROGRAM WITH COMMAND LINE:
%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\PowerShell.exe -NonInteractive -WindowStyle Hidden -noprofile -ExecutionPolicy Bypass -file .\PrinterInvRegSetup.ps1
2) CAPTURE CURRENT USER’S PRINTERS AND WRITE THOSE ENTRIES TO THE ABOVE CREATED REGISTRY KEYS.
Create a SCCM package
The package should be run only when a user is logged in.
POWERSHELL PACKAGE 2 (Main):
$printers = Get-WMIObject -class Win32_Printer -ErrorAction SilentlyContinue|select-Object -Property ServerName,ShareName,Location,DriverName,PrintProcessor,PortName,Local |Where-Object {$_.Local -ne $true}-ErrorAction SilentlyContinue
ForEach($printer in $printers){
$PServerName= $printer.ServerName -replace ('\\','')
$PShareName = $printer.ShareName
$PLocation = $printer.Location
$PDriverName = $printer.DriverName
$PPrintProcessor = $printer.PrintProcessor
$PPortName = $printer.PortName
if ((Test-Path HKLM:\SOFTWARE\SCCMINVENTORY\NETWORKPRINTERS)) {
if ((Test-Path "HKLM:\SOFTWARE\SCCMINVENTORY\NETWORKPRINTERS\$PShareName on $PServerName")) {
Remove-item "HKLM:\SOFTWARE\SCCMINVENTORY\NETWORKPRINTERS\$PShareName on $PServerName" -Force -ErrorAction SilentlyContinue
New-item "HKLM:\SOFTWARE\SCCMINVENTORY\NETWORKPRINTERS\$PShareName on $PServerName" -ErrorAction SilentlyContinue
New-ItemProperty "HKLM:\SOFTWARE\SCCMINVENTORY\NETWORKPRINTERS\$PShareName on $PServerName" -Name "PrintServer" -Value $PServerName -PropertyType "String" -ErrorAction SilentlyContinue
New-ItemProperty "HKLM:\SOFTWARE\SCCMINVENTORY\NETWORKPRINTERS\$PShareName on $PServerName" -Name "PrinterQueue" -Value $PShareName -PropertyType "String" -ErrorAction SilentlyContinue
New-ItemProperty "HKLM:\SOFTWARE\SCCMINVENTORY\NETWORKPRINTERS\$PShareName on $PServerName" -Name "PrinterLocation" -Value $PLocation -PropertyType "String" -ErrorAction SilentlyContinue
New-ItemProperty "HKLM:\SOFTWARE\SCCMINVENTORY\NETWORKPRINTERS\$PShareName on $PServerName" -Name "PrinterDriver" -Value $PDriverName -PropertyType "String" -ErrorAction SilentlyContinue
New-ItemProperty "HKLM:\SOFTWARE\SCCMINVENTORY\NETWORKPRINTERS\$PShareName on $PServerName" -Name "PrintProcessor" -Value $PPrintProcessor -PropertyType "String" -ErrorAction SilentlyContinue
New-ItemProperty "HKLM:\SOFTWARE\SCCMINVENTORY\NETWORKPRINTERS\$PShareName on $PServerName" -Name "PrinterPortName" -Value $PPortName -PropertyType "String" -ErrorAction SilentlyContinue
New-ItemProperty "HKLM:\SOFTWARE\SCCMINVENTORY\NETWORKPRINTERS\$PShareName on $PServerName" -Name "DateInventoried" -Value $(get-date) -PropertyType "String" -ErrorAction SilentlyContinue
SAVE POWERSHELL FILE AS: NetworkPrinterInventory.ps1
SETUP THE SCCM PACKAGE/PROGRAM WITH COMMAND LINE:
%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\PowerShell.exe -NonInteractive -WindowStyle Hidden -noprofile -ExecutionPolicy Bypass -file .\NetworkPrinterInventory.ps1
3) CREATE A DEPLOYMENT AND SET IT TO ‘RUN ALWAYS’ AND MAKE IT A REQUIREMENT.
Now deploy the second package and set the first package as a prerequisite (Check the box – Always run the prerequisite package)
The deployment should be set to run every 4 hours and ‘Always rerun’. Mark the deployment as required. 
4) ADD THE FOLLOWING IN BETWEEN THE EXTENSION SECTION WITHIN YOUR CONFIGURATION.MOF.
//========================
// Added extensions Start
//========================
#pragma namespace ("\\\\.\\root\\cimv2")
#pragma deleteclass("NETWORKPRINTERS", NOFAIL)
[dynamic, provider("RegProv"), ClassContext("Local|HKEY_LOCAL_MACHINE\\SOFTWARE\\SCCMINVENTORY\\NETWORKPRINTERS")]
Class NETWORKPRINTERS
[key] string KeyName;
[PropertyContext("PrintServer")] String PrintServer;
[PropertyContext("PrinterQueue")] String PrinterQueue;
[PropertyContext("PrinterLocation")] String PrinterLocation;
[PropertyContext("PrinterDriver")] String PrinterDriver;
[PropertyContext("PrintProcessor")] String PrintProcessor;
[PropertyContext("PrinterPortName")] String PrinterPortName;
[PropertyContext("DateInventoried")] String DateInventoried;
//========================
// Added extensions end
//========================
5) SAVE THE BELOW DATA INTO A FILE CALLED ‘AWESOME.MOF’.
#pragma namespace (“\\\\.\\root\\cimv2\\SMS”)
#pragma deleteclass(“NETWORKPRINTERS”, NOFAIL)
[SMS_Report(TRUE),SMS_Group_Name("NETWORKPRINTERS"),SMS_Class_ID("NETWORKPRINTERS")]
Class NETWORKPRINTERS: SMS_Class_Template
[SMS_Report(TRUE),key] string KeyName;
[SMS_Report(TRUE)] String PrintServer;
[SMS_Report(TRUE)] String PrinterQueue;
[SMS_Report(TRUE)] String PrinterLocation;
[SMS_Report(TRUE)] String PrinterDriver;
[SMS_Report(TRUE)] String PrintProcessor;
[SMS_Report(TRUE)] String PrinterPortName;
[SMS_Report(TRUE)] String DateInventoried;
6) IMPORT ‘AWESOME.MOF’ INTO SCCM DEFAULT CLIENT SETTINGS.
Either import the above MOF file into the Client Setting/Default Client Settings/Hardware Inventory/Classes/Import. Select the option to import every thing.
Alternatively, if you have compiled the MOF manually on the PC, Add a new reporting class by clicking the ‘Add’ button and connecting to the PC and selecting the WMI class ‘NETWORKPRINTERS‘
and that is it. The SCCM resource explorer should soon see the Network Printers.
Now, this is a convoluted process but this is the only way I can inventory Network printers. Any ideas or suggestions?

Answer 1

All the other ways are similar because this is a per-user setting.
