@dubst3pp4 hplib and it's done ? PPD file are also provided if you want to go "manual" ^^' archlinux, as always, has good "Linux generic" documentation https://wiki.archlinux.org/title/CUPS/Printer-specific_problems#HPLIP :)
@df5t0rw unfortunately not. Installing hplip was not a pleasure but a lot of manual work. Now the HP GUI detects the printer, but as soon as it was added, it immediately disappears from the list. Never had such trouble with a printer like this one...
@dubst3pp4 what is the model of the printer ? In any case, a CUPs server with the correct driver (extracted from hplip) do work, there is not so much to do with a regular system.
I mean if you have systemd and hplib, that's about it. If you have openrc there is indeed a loot of manual actions to do. There is also some systemd service to launch for network discovery. But if it work via usb, the problem is not "printer related" anymore :)
