Ports and protocols
Is SNMP enabled in your environment across all subnets?
o If not, please describe the subnets where SNMP is disabled and if it is possible to enable SNMP.
What versions of SNMP (SNMP v1, v2, v3, other) are enabled in your network infrastructure?
Verify that "Get Community" names values are consistent.
o Bi-directional communication between the HP UPD and printer is required to gather product specific
configuration information.
Make sure mDNS broadcasts and IP multicast services are allowed on the network for the HP UPD to discover
products.
o In dynamic mode, the HP UPD will only discover products within the same subnet when Search for
network printers is selected.
Activate the mDNS protocol on the printer/product using the HP Embedded Web Server (EWS).
Make sure a firewall or router is properly configured to allow the HP UPD to communicate over the necessary
network ports.
