It is and most printers have that ability.
The presentation of the option is usually the thing that make or break it for the users.
Printers where the enable/disable feature is listed with the SNMP configuration generally figure it out, but some printers have a special section where it list all services with the option to enable/disable them and when SNMP is listed together with IPP, mail print and the like, then a security consiscious user might disable it, thinking its just another unused printing protocol.
