1. Typically auto enter is used if you are scanning with a key wedge service such as DataWedge and you want to automatically (for example) submit a form after the scan has occurred.

Perhaps I am mis-understanding the use case here.
2. Yes, it is part of the reader specific parameters, ScannerConfig.ReaderParameters.ReaderSpecifics.ImagerSpecifics - Zebra Technologies TechDocs for Imager scanners. If you have a laser scanner then use the laser parameter: ScannerConfig.ReaderParameters.ReaderSpecifics.LaserSpecifics - Zebra Technologies TechDocs for camera scanners use ScannerConfig.ReaderParameters.ReaderSpecifics.CameraSpecifics - Zebra Technologies TechDocs
