Hi Walter,
Most likely, your printer does not use its MAC as the DHCP client
identifier, but a combination of its MAC and others. If you do "debug ip
dhcp server packet" on your router, and unplug/plug your printer, you will
be able to see the DHCP Client ID used by Printer. Use that value in your
router config, instead of the printer MAC, then you should be fine.
As the Client ID used by Printer dit not match the one defined in your
config, the router assigned the next available IP, in the DHCP dynamic pool,
which is 10.121.251.36.
Not sure the format used by your printer, but a Cisco router when works as a
DHCP client, use a long ID format of something like, which include MAC
address:
0063.6973.636f.2d30.3065.302e.3165.6238.2e65.6230.652d.4574.30
Check the link below for further details on the DHCP Client ID format.

Subject: Allocating Static IP Addresses with DHCP
Hi group,
Bellow is my configs to allocate static IP to my PC, but it is not
working as expected. It get allocated the next IP, i.e 10.121.251.36
instead of 10.121.251.35 as per the configs.
Do I miss something here?
ip dhcp excluded-address 10.121.251.33
ip dhcp excluded-address 10.121.251.34
!
ip dhcp pool Networks
network 10.121.251.32 255.255.255.240
