In JScript, you can handle the events defined by a class, but you cannot define your own.

Remarks

Fired when POS for .NET or the service object needs to alert the application of a device status change.

Examples are a change in the cash drawer position (open vs. closed), a change in a POS printer sensor (form present vs. absent), or a change in the power state of the device.

When a device is enabled, the service object may fire initial StatusUpdateEvents to inform the application of the device state. This behavior, however, is not required.
