While your problem is fixed, I'll still answer this question ...

An access point **should** act as merely a transparent bridge - 
bridging packets between the wired and wireless networks. So 
normally, a wireless client which sends a DHCP packet will have that 
packet bridged transparently across the network to be picked up by a 
server or relay agent.

This is not the only way to do it, but it is the normal way until you 
get up into larger networks with centrally managed access control and 
stuff like that.

Yes, but the printer will have received an ACK - so it is perfectly 
entitled to use the address. The fact that it later receives a NACK 
(from a different server) could be seen to be a problem.

Indeed, not the first, and won't be the last to fall for this. Even 
network professionals can do it - though in my defence, it wasn't me 
that decided to use a spare router as a small switch on a customer's 
network without disabling the DHCP server <whistle>
