This is the list of possible supported devices right now (USB only): http://www.sane-project.org/sane-backends.html http://www.sane-project.org/sane-backends.html But HP is a special case, they provide their own backend (hpaio, open-source) for SANE that is not integrated into sane-wasm ATM. http://www.sane-project.org/lists/sane-backends-external.html#S-HPAIO http://www.sane-project.org/lists/sane-backends-external.htm... If your device is on this list, it's NOT supported right now! But I do want to add hpaio soon, I also have access to an OfficeJet to test.
