If you are a lucky owner of scanner or MFP which works via network with
Apple devices, I have a good news for you: now your scanner works with
Linux as well!

In theory, this backend should work with any scanner that supports the
eSCL protocol (unofficially known as AirScan or AirPrint scanning). In
practice, it was tested on several devices from Canon, Kyocera and HP,
and this list constantly grows, though slowly, so feedback regarding
other devices is very welcomed.

Apple maintains a comprehensive list of compatible devices, but please
note, this list contains not only scanners and MFP, but pure printers as
well.

To use this backend, you don't need to install ScanGear from Canon,
HPLIP from HP or some other proprietary software from hardware
vendor. This backend works directly with your device and doesn't depend
on a 3rd party closed source components.

I've tested it using the provided Debian 10 packages (personal repo
hosted on software.opensuse.org) and it works.

It's GPL2+ but I still have to check if there are really no blobs

I'll try and make a Guix package, if I'll be able

HTH! Gio'
