The present disclosure relates to modifying files that are part of file system in a printer or printing device. The file system is related to a database, such that the database is updated when the file system is modified. Changes to the files system are made through a request, modifying the file system based on the request, and updating the database. Individual files make up programs that may be provided by a printer manufacturer or a third party solution provider. When the printer manufacturer or solution provider desires to modify files affecting a program, a query may be made as to the existing files in the database of the particular printer.

Printer based file revision databasing

A method of controlling usage of printer macros stored in a printer includes detecting a request for use of a first one of the printer macros by a print job. Printer identification information contained in the first printer macro is compared to a printer identifier stored in the printer. Usage of the first printer macro by the printer is controlled based on the comparison.

Controlling printer macro usage based on printer identification information

A method of printing a print job includes separating a print job into subsections, and identifying a subsection access level for the subsections of the print job. A requesting party is also provided with an access level that is determined. In one embodiment, the requesting party's access level is placed in a print job by a print driver program of a requesting party. The subsection access level and the requesting party access level are compared, and the subsections of the print job that have a subsection access level meeting the requesting party access level are printed. A system for secure printing of a print job includes a processor, a storage device, a printer, and software operable on the processor to identify subsections of a print job, and identify a subsection access level for the subsections of the print job. The system includes media that includes instructions operable on a processor to identify subsections of a print job, and identify a subsection access level for the subsections of the print job.
