ABSTRACT:
A system for managing printing system memory in which a state of a printing system subsystem is altered between a first state and a second state by reference to a substrate including machine readable code, such as bar code. The system includes a raster image processing device for scanning the substrate to read a representation of the machine readable code. In response to receiving an authorization signal, a value in memory is altered and the state of the printing system subsystem is changed from the first state to the second state.
