Web Services for Devices
Web Services for Devices or Web Services on Devices is a Microsoft API to enable programming connections to web service enabled devices, such as printers, scanners and file shares. Such devices conform to the Devices Profile for Web Services. It is an extensible framework that serves as a replacement for older Windows networking functions and a common framework for allowing access to new device APIs.Operation
The Microsoft Web Services for Devices API uses WS-Discovery for device discovery. Devices that connect to the WSDAPI must implement the DPWS.
