Almost there

I’ve been trying to get this to work on a Color Laserjet m451dn but each time I just recieve UNKNOW -OID not found! When I do CONSUM TEST I receive the same error. running the check from the terminal works just fine when I do it ./check_snmp_printer -H 192.168.4.50 -C public -x “CONSUM ALL” -w 20 -c 10

I’m stuck.
