Following are the various types of discoveries performed by HP Web Jetadmin. There are two distinct types of discoveries:

●Network Connected Device Discoveries: Find devices on your network. HP Web Jetadmin always follows the node-discovery with SNMP queries in order to resolve devices. Once the SNMP query resolves a device, it is placed in the All Devices list. Resolved devices include any HP Jetdirect connected hardcopy device, any third party hardcopy device, some HP network scanners, some HP network projectors, and more. See How HP Web Jetadmin Discovers Network Devices on page 126.

●PC-Connected Device Discoveries: Discovers PCs and then printers connected directly to them. This discovery facilitates both learning about devices that are connected directly to PC hosts and also gathers detailed information about those devices when the SNMP Proxy agent is being used. SNMP Proxy Agent is a small software package that can be installed onto a PC and facilitates HP Web Jetadmin communications with locally connected devices. PC-Connected device discoveries can be performed without the SNMP Proxy Agent being installed onto remote hosts but this type of discovery will only gather a minimal amount of device information. See How HP Web Jetadmin Discovers PC-Connected Devices on page 126.

Discovery methods are for the most part shared between PC-Connected and network device types. The following table shows which discovery option can be selected for each of the two discovery methods:
