As ippusbxd by itself is broken, meaning that it even does not work very well with the devices it is actually designed for, I am also in favor of removing it from all still supported Ubuntu versions (especially LTS). Then it does not block devices which could otherwise work better.
To the users whose device needed ippusbxd we should tell to install the ipp-usb Snap then, at it does the task of supporting IPP-over-USB devices correctly and to their full extent. ipp-usb Snap: https://snapcraft.io/ipp-usb ippusbxd replacement by ipp-usb: https://github.com/OpenPrinting/ippusbxd#before-you-begin-ippusbxd-or- ipp-usb -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to hplip in Ubuntu. https://bugs.launchpad.net/bugs/1871011 Title: USB scanning and printing broken on focal by ippusbxd (was: hpmud and ippusbxd conflict) Status in HPLIP: Invalid Status in hplip package in Ubuntu: Expired Status in ippusbxd package in Ubuntu: Confirmed Bug description: SOLUTION : sudo apt remove ippusbxd ---- Initial report ----- On Ubuntu 20.04 focal (with -proposed enabled).
