Add SANE firmware

Many scanners require firmware blobs which can be downloaded from the website of the scanner or extracted from the drivers they provide. Once you have the appropriate firmware you need to tell SANE where to find it in your configuration.nix:

{
  hardware.sane.enable = true;
  nixpkgs.config.sane.snapscanFirmware = pkgs.fetchurl {
    # https://wiki.ubuntuusers.de/Scanner/Epson_Perfection/#Unterstuetzte-Geraete
    url = "https://media-cdn.ubuntu-de.org/wiki/attachments/52/46/Esfw41.bin"; #Epson Perfection 2480
    sha256 = "00cv25v4xlrgp3di9bdfd07pffh9jq2j0hncmjv3c65m8bqhjglq";
  };
  # to build the gimp plugin
  nixpkgs.config.packageOverrides = pkgs: {
    xsaneGimp = pkgs.xsane.override { gimpSupport = true; }; 
  };
}

To enable the gimp plugin you also need to manually create a symlink:

ln -s /run/current-system/sw/bin/xsane ~/.gimp-2.8/plug-ins/xsane

Support for HP scanners

hardware.sane.extraBackends = [ pkgs.hplipWithPlugin ];

Non-root scanning

It seems like you might need to add group scanner to users which should be allowed to use scanner.

Enable Network Scanning

As of right now ( 2017-08-16 ) the sane backend does not support overriding according to the nixpkgs issue #17411. The workaround for this is to download the sane-extra-config.nix of michaelrus, put it into /etc/nixos/sane-extra-config.nix and use it in your configuration.nix via:

{ ... }:{
 imports = [
  ./sane-extra-config.nix
 ];
 ...
 hardware.sane.extraConfig."magicolor" = ''
   net 10.0.0.30 0x2098
 ''; # magicolor 1690mf
}
