There is no test for the HP variant of the GL841 in sane-find-scanner
yet. So as a first step you may have a look at
tools/check-usb-scanner.c, copy the tests for the gl841 to e.g.
gl841_hp, modify them so the scanner is detected. If the test that
sends actual commands works it's most probably a GL841.
See also the gl646/gl646_hp tests for an example.

Please tell us about the result and send a patch when you are ready.

Good luck!
