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

[MR ZenWiz]

I routinely use my Xubuntu 14.04.3 laptop, at my lady friend's house,
where she has an HP Envy 4500 all in one on her wireless network.

Xsane can't seem to find the scanner.

I've edited the /etc/sane.d/net.conf to this:

# This is the net backend config file.

## net backend options
# Timeout for the initial connection to saned. This will prevent the backend
# from blocking for several minutes trying to connect to an unresponsive
# saned host (network outage, host down, ...). Value in seconds.
# connect_timeout = 60

## saned hosts
# Each line names a host to attach to.
# If you list "localhost" then your backends can be accessed either
# directly or through the net backend.  Going through the net backend
# may be necessary to access devices that need special privileges.
localhost

As far as I can tell, this require the hp5590 driver, which appears to
be installed on my machine:

mar at mar8710w:~ $ loc hp5590
/usr/lib/x86_64-linux-gnu/sane/libsane-hp5590.la
/usr/lib/x86_64-linux-gnu/sane/libsane-hp5590.so.1
/usr/lib/x86_64-linux-gnu/sane/libsane-hp5590.so.1.0.23
/usr/share/man/man5/sane-hp5590.5.gz

And the dll.conf has net and hp both uncommented.

What am I missing?

Thanks.
