I don't know about that, but that was from 2015. It worked out of the 
box for me on Linux Mint 19.3.

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

If so, then we should be good on that side, at least from the network 
perspective.

On the laptop, could you try this and post the output?

SANE_DEBUG_NET=50 scanimage -L

Cheers,
