I have an ssid setup for Zebra printers due to the endless headaches with these things and dot1x.. It is locked down with a long and random WPA2-PSK and also dhcp fingerprinting.
Customer procurred some new models, and lo and behold they have a different dhcp fingerprint. This fingerprint is not listed in Clearpass.
I remember my SE saying we could submit new fingerprints for inclusion.
I can't remember where/who to send to though.
