My guess is that the issue for support is that it's very much an edge-case, and not something most in support would encounter. The feature is most likely only available do to refurb or transfer inventory across regions.

That being said, the reason it works so poorly might be because there's a lack of continuity within HPs printer line up. For obvious reason I haven't used an HP products in years, but even going back, there seemed to be little lineage within their InkJet printers. The fact that a tools was still available is amazing.
