Please consider the following for inclusion in the Release Notes for bullseye. Thanks, Brian. ======================================================================= Driverless scanning is the ability to scan without using a vendor backend driver, free or non-free. It is mainly associated with modern multi-function devices, but some modern standalone scanners are known to work driverless. "Modern" refers to devices that have been marketed in the past five years or so. The official SANE driverless backend is provided by sane-escl in libsane1 [1]. An independently developed driverless backend is sane-airscan [2]. Both backends understand the eSCL protocol [3] but sane-airscan can also use the WSD protocol [4]. Users should consider having both backends on their systems. eSCL and WSD are network protocols. Consequently they will operate over a USB connection if the device is an IPP-over-USB device [5]. Note that libsane1 has ipp-usb [6] as a recommended package. This leads to a suitable device being automatically set up to use a driverless backend driver when it is connected to a USB port.
