5. The printing system in accordance with claim 4, wherein each cluster has a cluster name, each printing device of the plurality of printing devices further comprising a storage device accessible by the processor for storing the cluster name of the cluster in which the respective printing device is included.

6. The printing system in accordance with claim 5, wherein the cluster name stored by the storage device of the second printing device defaults to the RFID identifier stored by the RFID tag associated with the second printing device.

7. The printing system in accordance with claim 5, wherein responsive to the RFID reader device of the first printing device sensing the RFID tag of the second printing device and retrieving the RFID identifier stored by the sensed RFID tag, the processor of the first printing device executes the application software for configuring the cluster including the first and second printing devices according to a clustering process comprising:

requesting via the network the cluster name stored by the storage device of the printing device of the plurality of printing devices that has an associated RFID identifier that substantially matches the retrieved RFID identifier;

comparing the cluster name stored by the storage device of the first printing device with the cluster name received via the requesting; and

selecting a cluster name from the compared cluster names to be the cluster name of the cluster; and

wherein the storage device of each of the first and second printing devices stores the selected cluster name as the cluster name of the cluster configured to include the first and second printing devices.

8. The printing system in accordance with claim 7, wherein the processor of the first printing device executing the application software for retrieving the RFID identifier stores the RFID identifier in its storage device, determines if the retrieved RFID identifier substantially matches any previously stored RFID identifiers prior to requesting the cluster name, and terminates the clustering process in response to a positive determination.

9. The printing system in accordance with claim 7, wherein storing the selected cluster name by one of the first and second printing devices includes replacing a previously stored cluster name with the selected cluster name.

10. The printing system in accordance with claim 7, wherein the cluster name of each of the clusters of the at least one cluster are ordered, and the processor of the first printing device executes the application software for selecting the cluster name in accordance with the ordering.

11. The printing system in accordance with claim 9, wherein the processor of the first printing device executes the application software for transmitting a message via the network announcing replacement of the previously stored cluster name with the selected cluster name.

12. The printing system in accordance with claim 11, wherein the processor of the first printing device transmits the message announcing the replacement of the cluster name via at least one of a multicast and a broadcast.

13. The printing system in accordance with claim 11, wherein the processor of each printing device of the plurality of printing devices executes application software for processing a received message announcing the replacement for determining if its stored cluster name substantially matches the announced previously stored cluster name, and replaces its stored cluster name with the announced previously stored cluster name responsive to a positive determination.
