I used the DHCP reservation option to reserve an IP address for my printer.  The DHCP IP Address Range is 100 to 199,  I choose 192.168.2.197 for the printer.  I found the printer in the drop-down "Computer Name" list on the right and left the MAC address and computer name as the default the populated from the drop-down.  I tried using the IP address that populated with the drop-down and I also tried setting it as 197.  Everytime the printer is shut off and powered back on the printer gets a new IP address.
Am I missing something here?
