Good.

'scanimage -L' offers you three backends for scanning: escl, hpaio
and airscan.

hpaio can never work while the ipp-usb service is active. This is a
feature of IPP-over-USB. It is not an hpaio bug.

escl is capable of working with ipp-usb but does not. This seems to
be a bug in SANE's libsane-escl, so I am reassigning your report to
libsane1.

airscan is an alternative to escl and, fortunately, does work.
