Well, we ordered a new office printer as the old one is finally falling to bits (literally).
It was in fact ordered minutes before my new mandate that we only buy IPv6 capable kit :-)
However, it arrives, and yes, does IPv6. In fact the IPv6 "just worked" and it took them a few minutes to sort the IPv4...
It just goes to show that some manufacturers heeded the many warnings that came out back in 2007 and started actually including IPv6 in their development processes.
