Didnt know you could do that. Must be using a crossover cable
tex
yers ago, you needed a crossover cable.
now devices "autonegotiate" and reverse the 2 pairs of connectors so crossover is no longer necessary
HOWEVER
ir is recommended by microsoft NOT to connect this way. it will often work, but cn drop out in the middle of print jobs and cause all sorts of problems
always best to use a network switch (or 2 ports on your router).. this eliminates all sorts of problems. we never hook up with a single cable except as a quick test
