The WiaSane project provides a Windows Image Acquisition (WIA) Driver which enables image acquisition from scanner devices through the Scanner Access Now Easy (SANE) network protocol.
This WIA driver implements a SANE frontend on top of the SANE network protocol. It is referred to as Scanner Access Now Easy - WIA Driver.
In order to access those scanner devices either the scanner itself or a SANE daemon needs to provide a SANE network frontend to be used.
