You could also try (on the laptop):
SANE_NET_HOSTS=192.168.1.16 scanimage -L
... replacing the IP with that of your main machine.
This should explicitly add the IP to the list of hosts that would be
considered in addition to what is configured.
I just tried that and it worked for me.

Okay, here is the net.conf file:
home-E7250:~$ sudo cat /etc/sane.d/net.conf
# 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
#
192.168.0.15
And when I ran the command:
home-E7250:~$ SANE_NET_HOSTS=192.168.0.15 scanimage -L
This is really weird.
One thing I should ask: have you built SANE on the laptop from sources?
Is there a possibility that there is a mixture of package and locally
built objects on there?
Assuming not... we continue... :D
If the IP is in the config file, we should be seeing something like:
[net] sane_init: searching for config file
[net] add_device: adding backend 192.168.0.15
[net] add_device: backend 192.168.0.15 added
[net] sane_init: done reading config
...as the backend parses the config file. That's what I don't understand
about what we are seeing.
Could you give us the debug of scanimage when you specify the IP via the
environment variable?
SANE_DEBUG_NET=50 SANE_NET_HOSTS=192.168.0.15 scanimage -L
We should expect to see something like:
[net] sane_init: evaluating environment variable SANE_NET_HOSTS
[net] sane_init: trying to add 192.168.0.15
[net] add_device: adding backend 192.168.0.15
[net] add_device: backend 192.168.0.15 added
It might also be useful to see the output of this:
SANE_DEBUG_DLL=10 scanimage -L
...to make sure we are getting the right binaries.
