Enable Printing LPAC Sandbox

Computer and userIntune-readyPrintingLPACSandboxEnabled

Supported on Microsoft Windows 7 or later

155.0.8059.85

What it does

Setting the policy to Enabled or leaving it unset enables the LPAC Sandbox for printing services whenever the system configuration supports it. Setting the policy to Disabled has a detrimental effect on Google Chrome's security as services used for printing might run in a weaker sandbox configuration. Only turn off the policy if there are compatibility issues with third party software that prevent printing services from operating correctly inside the LPAC Sandbox.

What it writes

Hive: HKEY_LOCAL_MACHINE or HKEY_CURRENT_USER
Registry key: Software\Policies\Google\Chrome
Value name: PrintingLPACSandboxEnabled
When enabled: DWORD 1

The OMA-URI is an inferred ADMX-backed Policy CSP candidate derived from the source ADMX file name and policy name.
Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
