This system provides a routine for carrying out an interrupt between a control tool, such as a printer, and the controlling processor for carrying out interrupts in the printer which are generated by the processor. The primary purpose of the routine is to distinguish a true interrupt from noise, which is much shorter in duration. The problem is resolved by adding a status check in the interrupt routine.
