Why not just use wireless networking modules? Two Radio Control
TX/RX's have got to be a lot more money than just two wireless network
cards.
Plus using RC sets or garage door openers this way is just as illegal
as using a CB radio channel. Most printers require two way communication.
Range should not be a problem, but even if it is, I have a ton of
links in the Links area on 2.4GHz antennas.
