I traced the problem to
https://sourceforge.net/p/hplip/mailman/hplip-devel/thread/46a1257e.5060...@cab.cnea.gov.ar/
tl;dr: hplip changed and now the hpaio backend no longer ignores the
local_only flag. In the past, saned/hpaio was able to access network
printers, even though saned asked it
Hey,
We have a scanner available through a network and since we wanted to
avoid having to install the hplip drivers on all workstations, we
thought we'd employ saned to make the scanner available on the
network.
This worked fine until we upgraded to Debian jessie / sane 1.0.24
(from 1.0.22).
