OK, let's try to narrow this down a bit.
I have to ask the obvious: does the main machine have a firewall installed?
Next, let's make sure that the saned service is running properly.
On the main machine, saned listens on port 6566.
If you try:
netstat -an | grep 6566
... do you see this or something similar?
tcp6 0 0 :::6566 :::* LISTEN
I see exactly that when I run netstat. That makes me wonder. I have
disabled IPv6 on the interface that connects to my local network on
both devices (due to an unrelated issue). Maybe there is somewhere
that I should specify that I want to use IPv4?
The output from the scanimage command is:

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

Interesting.
It is possible that saned is having permissions issues accessing the
devices locally, and therefore not advertising them to your laptop, but
let's not assume that yet.
On my remote machine, I see:
[net] connect_dev: trying to connect to 192.168.1.16
..but I don't see anything like that there.
Could you give us a dump of your laptop's /etc/sane.d/net.conf?
Cheers,
