I'm building a sw that should be able to read the papers read from a scanner and process them with a minimal user interaction, basically I don't want the user to jump into another sw, output an image or doc, and insert that into my sw, this kind of problem seems to be fixed when it comes to printers printing, but I couldn't find something similar for scanners (paper scanners especially, I have no use for QR and barcode scanners), the best I could find is USB HID interface, which seems pretty low level and if I'm not wrong device-specific so I have to write the implementation for each model I need to support (please correct me if I'm wrong), I know this is a Linux community but does Windows have something similar too (my sw will probably need to run on it)
Sorry if this isn't the most suitable community
Yes, you can now use AirScan (also called something else I don't recall currently) for "driverless" scanning.
No, it's a cross platform standard. You can even run a server on Linux interfacing with SANE to convert older scanners.
I looked up the non-Apple name and it's eSCL. That's a lot easier to search for.
