I have a scanner in HP Photosmart C3100 series. Using simple-scan I get the information that I need to install the driver sane-hpaio.
But simple-scan has sane-backends as input for which the Guix source file says "This variant links in the hpaio backend, provided by hplip". So somehow simple-scan does not find ~/.guix-profile/lib/sane/hpaio.so.1 (which exists). It actually works when I call it as follows: LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:$HOME/.guix-profile/lib" simple-scan But this cannot be the proper solution.
