Steven, Thanks for sharing. A real example is just what the doctor ordered. In your below example, did the print transaction rely on TCP at L4? I've captured some print traffic on our corp. network in the past and I'm pretty sure it was TCP. Don't know if there was a speed mismatch between the server and the printer though.
