Please uninstall ippusbxd. Then your device should work with HPLIP normally. ippusbxd wa supposed to allow driverless printing and scanning without HPLIP. Unfortunately there were problems in its design.
In Groovy we will replace ippusbxd by ipp-usb which finally allows driverless printing and scanning without HPLIP to work reliably.
