Hi, Antonio, Seems that for some HP printers there is need for a propietary plugin that must match exactly hplip version. While you can download the plugin, I suggest to try installing the 'sane-airscan' package and see what happens. Your printer/scanner may work driverless as scanner with sane-airscan (using the eSCL/airscan protocol), and that does not require HPLIP. Hope this helps, -- Agustin
