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.
Best wishes,
Arne

I have a USB-connected HP DeskJet Ink Advantage 1515 printer/scanner.
On my own system (this is a full Guix System, not Guix on a foreign distro) I modified the configuration.scm:
```scheme
(use-package-modules #;... scanner)
(operating-system
#;...
(services
(append
#;...
(modify-services %desktop-services
(sane-service-type _ => sane-backends))))
#;...)
```
After `sudo guix system reconfigure configuration.scm`, `simple-scan` still could not find it. However, on reboot, it was able to find my already-connected USB printer/scanner without any issues.
Perhaps only some kind of force-trigger of `udev` would be needed after the above setup, but `udev` is pretty early in the Shepherd tree.
On the other hand the `sane-service-type` documentation in `info guix` is ***severely*** lacking, and the documentation is somehow lost in the middle of documentation about geolocation services, so it should probably be fixed.
Thanks
