In brief, success with basic scanning after installing and selecting
sane-airscan.
Thank you Brian (and pabs that was trying to suggest this to me in IRC)!
The ipp-usb package was installed, but not sane-airscan (in this test Debian
build). For completeness, below is the output of the requested commands after
installing sane-airscan and rebooting (just in case to remove as many
variables).
It's unclear to me the relationship between SANE and CUPS in the context with
a dedicated scanner (makes sense with a MFD). Is configuring a CUPS
"print-queue" required? Not sure if there's a brief explanation, or pointer
where can one learn more about this? Clearly there is more testing to try,
and I'll read over wiki.d.o CUPSDriverlessPrinting.
Also, is there any quick info on the link between sane_open() and
sane_hpaio_open()? Expect it's a registered callback function, but where?
The SANE API docs seem more "front end" focused (e.g.
https://sane-project.gitlab.io/standard/api.html#sane-open).
I'll continue testing functionality further, and hope to share more findings
in the next week or so. This scanner is replacing a legacy HP Scanjet N6310,
which required a windows system. I'm so glad to shed that dependency with
this new unit. Many thanks again!
