Abstract
A printer system for and corresponding method of determining an arrangement of status objects forming a status tree structure used to represent hardware components contained within a printer and the status tree structure stored within a print engine of the printer. A change in operational condition of one of the hardware components are detected with a sensor. A state of a status object corresponding to the one of the hardware components is changed to have an active state. A name of the status object having the changed state is transmitted from the print engine to a controller. The status object having the changed state is queried for a root path of the status object with the controller.
