Your printer supports IPP over USB. It causes IPP over USB daemon to run and keep printer's USB ports open, which conflicts with hplip.bInterfaceClass 7 Printer bInterfaceSubClass 1 Printer bInterfaceProtocol 4
From now, you have two options:
1) Remove IPP over USB daemon, which will unblock hplip:
dnf erase ipp-usb
2) Remove hplip and scan driverlessly:
dnf erase hplip
dnf install sane-airscan
