My problem is that I still don't understand guix well enough: I don't know in which file to write this configuration of cups (name and path), nor with what tool to define it (nano, terminal, etc.). Perhaps I do not have enough computer background to use guix to date. It does not matter, I will eventually learn over time, not to mention that some functions will be automated with the evolution of the project, as is the case for the graphic installation.
