Indeed. And given SANE's design, there shouldn't be much need for it: it assumes that either the scanner is local (via a hardware-specific driver, hpaio being one of them) or it's remotely accessed over the SANE protocol, in which case it uses the DNS-SD protocol to find it. The problem is with scanner that are remote but using a "local driver" (local to the client rather than local to the scanner). I suggest you open a feature request on the SANE's issue tracker. Who knows, maybe this can even be solved already by somehow tweaking the DNS server to advertize your hpaio device? Stefan
