BOOTP/DHCP, Request from 00:40:8c:10:63:ab, length: 300

The fact that the printer thinks its on 192.168.100.x will make no 
difference to dnsmasq, (set dhcp-authoritative to be sure) but maybe 
your firewall rules will catch that packet? If dnsmasq isn't logging 
anything, it is not revceiving the the packet.

A DHCP client on an unconfigured interface should be sending packets 
with source address of 0.0.0.0 but my experience of printer DHCP 
implementations is that they are particularly buggy. (It's not HP, is it?)
