Abstract
An identification card printer for printing an identification card includes a print mechanism configured to print onto the identification card. A process signal input is configured to receive a process signal related to operation of the identification card printer. A memory contains a nominal process signal statistical parameter and a rule. A microprocessor is coupled to the memory and configured to receive the process signal from the process signal input and calculates a statistical parameter of the process signal. The microprocessor compares the calculated statistical parameter to the nominal statistical parameter based upon the rule and responsively provides an event output as a function of the comparison. The event output is related to an occurrence of an event during operation of the identification card printer.
