This output is fine. You have an IPP-over-USB device. See the Release
Notes for Debian 11.

This output is also fine and to be expected. If you unplug from USB, the
ipp-usb.service will be shown as "Inactive".
You did not give 'ippfind -T 5'. Did you try 'driverless' again? We need
the output from it.
Install the avahi-utils package and give
avahi-browse -rt _ipp._tcp
