Hello Gottfried,

I believe there is a permissions problem that prevents non-root users from accessing HP printers via USB. This is because the udev rules file that the hplip package provides somehow does not get installed in the system. To check, you can manually add the udev rules file to your system by adding the following service to the list of services in your system configuration: (udev-rules-service 'usb-hpaio (specification->package "hplip")) After reconfiguring, there should exist a file '/etc/udev/rules.d/56-hpmud.rules', which was not there before. After rebooting, run 'guix shell hplip -- hp-setup', select the USB option and hit 'Next' - the printer should show up now. With this setup I was able to print and scan with my HP printer over USB. Let me know if it works for you as well. Best, Lukas
