Patent ID: 8014015

Claim:
A print data processing system comprising: a printer for printing print data, which includes: an interface for sending and receiving data; a storage for storing the print data received via the interface therein; and a plurality of data processing indicating apparatuses, each of said apparatuses including an interface for sending the data, each of the data processing indicating apparatuses sending, to the printer via the interface: identification data of itself; name data of the print data; and any one among storage indicating data attached to the print data, the print data, and print indicating data of the print data stored in the storage, wherein the storage stores the name data, the identification data of the data processing indicating apparatus that has sent the storage indicating data, and identification data of the data processing indicating apparatus that has sent the print indicating data, the name data being related to the identification data of the data processing indicating apparatus that has sent the storage indicating data and the identification data of the data processing indicating apparatus that has sent the printer indicating data, wherein the printer further comprises a controller for performing operations of: updating the print data received by the printer and stored in the storage; and generating update notification data for notifying update of the print data, wherein the printer sends the update notification data to the data processing indicating apparatus corresponding to the identification data related to the name data of the updated print data via the interface, and wherein the controller of the printer further performs operations of: judging whether or not the identification data of the data processing apparatus for sending the print indicating data of the print data stored in the storage includes the identification data of the data processing apparatus that has sent the print indicating data of the received print data, when the printer receives the print data used for updating the print data stored in the storage from the data processing indicating apparatus for sending the storage indicating data of the print data stored in the storage; and deleting the identification data of the data processing apparatus for sending the print indicating data of the received print data among the identification data of the data processing apparatus for sending the print indicating data of the print data stored in the storage, when the judgment result shows that the identification data of the data processing apparatus for sending the print indicating data of the print data stored in the storage includes the identification data of the data processing apparatus that has sent the print indicating data of the received print data.
