Shivani,
this bug is one of the cases I mentioned in my last comment at https://bugs.launchpad.net/hplip/+bug/1883898 - 'some devices had plugin=0 set, but they needed a plugin anyway'.
It seems testing of the device wasn't done on clean OS - meaning there was a lingering plugin in OS, which was loaded correctly during testing, but a tester didn't know about it...
