The DCA is developed by PrintFleet, and the information retrieved is stored on their secure server. The DCA runs a service in the background and uses the SNMP protocol Port 161 within the Local Area Network and sends the information through HTTPS Port  443 (same ports used for accessing secure websites) to the PrintFleet server. The software needs to be installed on only one Windows device within the network – regardless of how many sub-net’s you have.

Please see the diagram below.
