Patent ID: 7739355

Claim:
A method for loading a program data for a graphical user interface for operation or for diagnosis of a printer or copier, comprising the steps of: transferring specification data stored in a first storage region of an internal control unit of the printer or copier from said internal control unit over a network to an external operating unit for the printer or copier which is external to the printer or copier with aid of a browser program module of the external operating unit and executed by the external operating unit, said external operating unit also having a browser module cache and an archive cache, the specification data containing at least a specification about at least one necessary program module necessary for generation of operating or diagnosis functions for said printer or copier; with help of the external operating unit, checking whether program data that contains said necessary program module are contained in said archive cache of the external operating unit in which program data are stored and read out independent of a network address of the printer or copier, and wherein a version state of the necessary program module stored as program data in said archive cache is compared with a desired version state of the necessary program module; and if the program data in the archive cache does not contain said necessary program module of the desired version state, transferring program data which contain said necessary program module of the desired version state from a further storage region of said internal control unit to the external operating unit and storing the program data with said necessary program module of the desired version state in the archive cache of the external operating unit; and executing instructions of said necessary program module by the external operating unit.
