Alas that you picked 10.1.1/24 for your internal network; that may well cause
you regret when you want to VPN in to an employer who also chose the same
range, or get a 3G router, or whatever else, in future.  Much better is to
pick your range like this:

bash -c 'echo "My network is: 10.$((32+RANDOM%192)).$((32+RANDOM%192))/24"'

That gives you a pretty reasonable change of having a unique network block, so
no annoying connectivity problems in the future.

Anyway, unsolicited advice aside ...

You didn't say where these were connection, so I am guessing that the server
is on the wired network, and the netbook is on wireless, right?

In future, it helps to say that, because now I am just guessing at your
problem.  However: your wireless device shows that it uses the 192.168.1/24
range for "LAN and Wireless", and 10.1.1/24 for "WAN".

On these devices "WAN" usually means "the far side of a NAT layer", which
means that what you are seeing in terms of ssh (from wireless to wired, but
not wired to wireless) is more or less what I would expect.

Personally, I solved this by turning *off* all the routing, DHCP, DNS, etc
features on the wireless router, then plugging a *LAN* port on it into the
switch providing the internal network.

That makes it a wireless bridge, with DHCP served by the server on the LAN,
and no protection at all between wired or wireless clients.  For my set of
risks this was great.

I have no idea on this one: how are they wired up?  Which print software are
you using?  How did you configure it?  Can you ping / HTTP to the printer?

Heck, is it a "network sharing" connected USB printer hanging off the router,
or even the wireless AP?
