dhcpd will only use the assigned fixed-address if it would be valid for
the subnet that the printer is located on. In this case dhcpd thinks
otherwise, so ignores the statements in the host statement.

We need to see a bit more of your configuration file(s) to understand
what is going on. For example, you have two host entries with identical
contents - is this a slip of the cut and paste, or how it really is?
What is(are) the subnet definition(s) that contains 10.210.0.1,
10.210.109.244 and 10.210.6.43? Is it one big subnet, eg 10.210.0.0/16 ?

Remember host statements are in the global scope, so putting them
inside a subnet declaration does not automatically make them valid for
that subnet.

What version were you previously running that worked?
