Is the printer switched on?

Does the printer obey the rules for a hub or for a normal peripheral
device?

Unless the Mac sees what it believes to be a hub it will not allow the
connection to be switched to ethernet.

I don't know the full technical details of how ethernet works, but in
effect it is equivalent to expecting to see a carrier signal.  A hub
always puts out this 'carrier' whereas peripheral devices like computers
with switching capabilities look for it before switching.

It is for this reason that a crossover cable will not always work - and
will usually not work to connect two computers directly together.

Small hubs are not very expensive these days and will ensure much more
reliable connections appart from allowing more devices than just two to
be interconnected.
