I think you just missed it, until Win7 there was a Telnet client. You
can install/enable one (genuine MS) on 8, I have done it but a while
ago, the details are out there somewhere.

Either way should work, only 10Mbit Ethernet connections cannot do this
without a crossover cable, and are usually the best ways of talking to a
new network device, without other devices adding confusion. Network
Manager can be persuaded to create a new fixed IP address configuration
to set your laptop to something in the 192.168.1. network. If you do
not mark it 'Auto', NM will not attempt to use it without explicitly
being told to, or of course you can delete the connection after use.

Yes, there are simpler ways to set a fixed address, but if you already
have NM running, it is easier to work with it than against it.

You can, just about, persuade Win8 to use a fixed address, but NM is
far easier.

Yes.

A printer, being a server, generally has a fixed IP address, and
Windows will need to be given it. Modern printers often have an LCD
display through which configurations can be made. I'd expect one with
an Ethernet port to run a simple web server for configuration.

Best not go there... you shouldn't need to disturb anything. If the
router is indeed running DHCP, and that would be expected in this sort
of network, then you do really need to know its IP address range, for
which you will need to login with the admin password, but you don't
need to see it physically. If this password is unavailable, and it may
well still be whatever Google tells you is the factory default for
this model, then try setting the printer to the address adjacent to the
router's. The chances are that the router address pool has a gap of
several addresses around that of the router.

If you really want to get fancy and you have admin access to the
router, you can set the printer to DHCP, note its MAC address and then
tell the router DHCP server to make a reservation for a particular
address for the printer within its pool. It will then always give this
address to the printer, but by DHCP.
