[sane-devel] Xsane can't find network scanner

[Paul Newall]

I don't really know what hplip installs where, but I'd guess that it installs the sane backend hpaio for scanning, a cups filter for printing, and the hplips toolbox which allows you to look at the status of the printer (ink levels etc). I can tell I have hplips installed since it is in the desktop menu (In settings). After installing hplip I could setup the printer from the menu: Settings/Print settings, but I could not scan until I made the link described below.

from MR ZenWiz 17/10/15
I show hpaio in the /usr/lib/sane directory as well, but not  hplip.

How do I know if that is installed for sane?  It is all over the place
elsewhere on this machine.

Thanks.
