Claim:
A printing system comprising: a network, a print controller connected to the network, and a printer connected to the network; the print controller including: a print-controller-side transceiver that transmits commands and data to and receives commands and data from the printer over the network; and a print-controller-side controller that controls the print-controller-side transceiver to selectively transmit to the printer a storage command commanding the printer to store data, a retrieval command commanding the printer to retrieve and transmit stored data, and an update command commanding the printer to update stored data; and the printer including: a printer-side transceiver that transmits commands and data to and receives commands and data from the print controller over the network; a storage unit that stores data; and a printer-side controller that, upon receipt of a storage command, stores data in the storage unit, and, upon receipt of a retrieval command, controls the storage unit to retrieve data indicated by the retrieval command and controls the printer-side transceiver to transmit the retrieved data to the print controller; the print controller further including an amender that amends data retrieved by and transmitted from the printer as a result of the retrieval command, the print-controller-side transceiver transmitting the amended data to the printer; wherein the printer-side controller, upon receipt of an update command, updates data stored in the storage unit based on the amended data from the print controller.
