I submitted this question on Ask Different but it is also clearly a network engineering question (my tool is tcpdump here :) ):

[How to make shared printing works on an IPv4 only network?][1]

Do you have any idea on how to solve this problem?

Do you think this question would get a better answer in Network Engineering?

My problem stands at the frontier between network engineering, system engineering (Unix & MacOS X oriented). So my hidden question was: on which group will it be the most efficient to submit this question so as to avoid repetting questions and dissiminated answers?
