Abstract

An improved networked system having a host computer and multiple printers is provided in which the printers have a bi-directional data communications capability and have at least one memory device capable of storing print data and other types of data files. The host computer can be utilized by a user or a Network Administrator to 'read' the contents of each memory device on each printer connected to the network that has the NPAP bi-directional communications capability. The user/Network Administrator can de-fragment data files (e.g., print job files) on a flash RAM memory device, or can format one of the memory devices of a printer (which deletes all of the files stored on that memory device). Furthermore, the user/Network Administrator can transfer a file from the memory of one of the printers on the network to the memory of a second of the printers on the network. When a given resource management function has been completed, an updated resource directory is automatically displayed at the host which includes all of the changes resulting from the earlier resource management function command. Once the printer receives an NPAP command of the type that accesses the resource management capabilities of the printer, the printer's Emulation Manager will control the execution of the resource management function that has been received. The Emulation Manager communicates the command along with the required arguments to the Common File System, which performs the actual data manipulation of any of the files in the memory devices.
