All programs written with the BarTender Print SDK will rely on the Engine class to provide BarTender print functionality. The BarTender Print EngineThe BarTender process provides standard BarTender functionality, such as opening label formats, changing label settings, and printing. The BarTender background process is controlled using an instance of the Engine class. The Role of the Engine ClassThe Engine class contains many methods, properties, and events to assist in printing and controlling the BarTender Print Engine. Features of the Engine ClassThe Engine class allows users to: Start, stop, and restart a BarTender background process. Open, access, and save label formats. Use Engine-level events to monitor printing. Manage the BarTender Application window.How To: Start and Stop an EngineAn engine must be created and started in order to launch a BarTender process and commence printing. The Engine class provides the Engine.Stop method to explicitly shut down the BarTender Print Engine. If the engine is not stopped, a bartend.exe process may be left running in the background. After calling the Engine.Stop method, it is best practice to call the Engine.Dispose method. The Dispose method ensures all non-memory resources are properly released for t
