Seems an inelegant solution, but if the above is *all* that is required
then a WRT54G could do the job. Have the uplink/WAN port be on one
network, and the printer being part of the other. The printer does appear
on one of the two networks, but the above doesn't strictly disallow this.

I'm unsure whether it will beat the price of the already suggested
options, but a pair of WRT54Gs could be used and make a full DMZ network
for the printer.
