Open the EveryonePrint Admin and click Settings. Under General Settings, at the top of the screen, the current licensing is displayed, including any existing license key and maintenance expiration date.
In the above example, the license is a EveryonePrint Connect Education license, with maintenance expiring in August 2017, which means EveryonePrint can be upgraded and updated free of charge until this date. When maintenance expires, it can be renewed. Maintenance is not required, but the software cannot be updated without valid maintenance.
