In my case (LaserJet Pro MFP M127fw), I can print without hplip, but not scan. But I'm using guix on a foreign (Debian) system, and haven't managed to set up hplip-plugin (from nonguix) yet. There is a list of which printers require the plugin at https://developers.hp.com/hp-linux-imaging-and-printing/binary_plugin.html My guess (and it is only a guess) would be that you will not have any luck with libsane if your printer shows up on that list.
