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.
