exclusion range or reservation

I have 4 Network printer/copiers that have been statically assigned an ip address on the machine itself.  They are not using DHCP.  I have not setup a reservation of these ip addresses on the server (WIN 2012)  Can you use an exclusion range for each ip address to have it not distributed or is the best way a reservation?

Ideally, you usually should control IP allocation from DHCP server, it's more convenient.
In your case, you can create the corresponding DHCP scope and exclude the IPs from distribution.

In exclude do you mean reserve or use an exclusion range?

While the same net result may be the same, exclusions and reservations are different.  Exclusions are to block off addresses that shouldn't be used, such as static addresses as you describe.  Reservations should be used to ensure devices that use DHCP, but need the same address, get that same address every time, which is *NOT* what you describe.

Now a reservation may be appropriate if you wanted to switch a printer to DHCP...and is actually what I'd recommend in most cases.  But if you choose to leave them static, then an exclusion is a better fit.

As Cliff mentioned,
Reservation is when the device is configured for DHCP (i.e. the NIC of the device configured with DHCP and you configure EXCLUSION from the existing scope in DHCP server to provide the pre-defined IP to the device once DHCP Request is sent from it across the network)

Exclusion is what applies to your case, where you have already defined the device with IP and you need to EXCLUDE that IP from being provided to any device on the network. You perform this in the properties of the corresponding DHCP scope.

Generally, the first approach is a bit more convenient, IMHO.
