I've just scanned my home network for SNMP enabled devices, first call was to check for community strings public and private (good practice to do and please never use those strings!!!).
My HP 6700 is listening and sending using public but I can't find it anywhere on the settings on the display scene and via the web GUI or in three different manuals for it on-line.
Indeed, the only mention of SNMP is that is in the specifications it is supported!
HP surely haven't made something with such a massive security flaw in that you can't change the settings or disable SNMP.
