An image processing method for use in a printer driver includes steps of receiving an instruction for a printing process, judging whether an image corresponding to a developed image signal represents a specified image according to the printing process, and outputting a result obtained in the judging step so as to use the result processing of the image signal. The transmitters are to transmit signals in frames including slots. The preferred embodiments of the articles contain that exhibits a UV absorptivity greater than or equal to 70 liters per gram-cm. The elongate opening permits fluids to pass between the at least one longitudinal lumen and locations external to the elongate catheter member, and defines a transverse dimension increasing from proximal to distal. The mixing subsystem is configured to receive and mix the transmit signal and the receive signal to produce an output signal.
