The ipp-usb service is active but neither 'driverless' nor ippfind see the printer and sane-airscan does not appear to work. You also cannot access the web interface. I am lost! The message ipp-usb is not ready for this device is coming from ipp-usb. It seems to me that this is the most important information you have supplied. I suggest you report this issue upsteam (give the error message). https://github.com/OpenPrinting/ipp-usb/issues You will have to sign up to github. > these commands can help you ? They help me to guide you to expert help. But you have been very helpful Cheers, Brian
