Android support for stateful DHCPv6 is missing/broken before 4.3,
according to
http://en.wikipedia.org/wiki/Comparison_of_IPv6_support_in_operating_systems
As for the printer, it's setting a "known" tag, which implies a
dhcp-host line, and then sending "No addresses available" which implies
possibly no suitable address.
Would it be possible to send me your dnsmasq config, off-list if you prefer?
Is there any chance you could try dnsmasq-2.66, which has many DHCPv6 fixes?
Cheers,
Simon.
