Indeed, it's not always a convenient option.
For me, the BananaPi homeserver was within reach of a USB cable, so it
was a no-brainer.

I could live with it, yes, but my wife expects the printer to "just
work", so it has to pretend it's always on.

It's definitely possible with SANE.  But apparently not with `hpaio`.

Yeah, I wish they'd just used SANE instead of inventing their own wheel.

At least they do use CUPS instead of reinventing yet another wheel.
