Where/what do I tell that the printer is called Print-1, this is the
bit that's not clear to me. Are you saying that I should give it this
name in teh router configuration?

Exactly! Much more sensible and easier IMHO, that's why I do it this
way too. :-)

Er, no, this is where we came in! I'm using dnsmasq on *one* machine
in the LAN and that means I only have to edit *one* /etc/hosts and
dnsmasq tells other machines on the network the contents of that one
/etc/hosts via DNS.
