Nathan,
Something like the below would work.
However, the test for being a member of office-printers or
public-printers would need to be changed. I didn't know what
parameter would cause that to be the case so I just used an example.
Also, you shouldn't need member KNOWN in your test unless you are
performing some reservations and only want clients in the
office-printers / public-printers classes that you have given a
reservation to. If so, you can assign special options during the
reservation process. That might satisfy the JetDirect requirements in
a simpler way. Have a look at:
https://kea.readthedocs.io/en/kea-2.2.0/arm/dhcp4-srv.html?highlight=reservation#including-specific-dhcpv4-options-in-reservations
avoiding the need for these other more complex classes.
