A managment station responds to an HTTP request for device discovery by spawning a device discovery task that creates a linked list and first broadcasts UDP based requests out on a subnetwork for devices on the same subnetwork to respond. Device information from responding network devices is stored in a linked list. This process is repeated until a specified length of time has expired. Then a second broadcast request is sent out that includes a list of printers that have responded so that they will nor keep responding. The list is updated by responses until there are no more responses. Any nodes in the linked list that still only have a network address are upadated by sending a unicast SNMP request those network addresses in order to get the additional information. The data from the linked list is sent back to the HTTP client.
