[sane-devel] HP officejet: access scanner over the network

Wed Jan 7 05:41:35 UTC 2009

Hello,

A little digging got me a small step further: Mandriva comes with a
backend for hpaio: libsane-hpaio it's called. Running scanimage in debug
mode I see the hpaio backend being registered, but there is no
configuration file or anything included in the rpm package. And
scanimage -L still does not find the scanner (of course: I haven't told
it which IP address to find this scanner).

Also I can not find a maillist for hplip or hpaio, and on the hplip
pages it's all about printing, not scanning.

Googling for libsane-hpaio also doesn't give any further information.
Except one link where someone indicates his scanimage -L can find the
networked scanner but no information on how that was configured :(

Oh well if really no-one knows thsi here I may just have to get myself a
10-m long USB cable or so.

Wouter.
