Possibly, but it will be via WEP-protected network. Changing a symmetric key via the encrypted channel is a bad idea: it was one of the methods by which Bletchley Park were able to crack Enigma (airforce traffic, if memory serves). I still have difficulty believing what a hash they made of WEP. Making the best of a bad situation, you could try changing the key quite often (~order 1 day), at pseudo random times, to try and catch "Eve" out. There's also the problem of a printer missing the key-change (from being switched off). This is all assuming the printers do have the facility for remote key management. It all sounds like a bit of a nightmare. Good luck!
