A print job is processed to produce printed output using a printing component of a device. An input/output device (of the device) is controlled by a processor of the device to output signals to finishing equipment. Such finishing equipment is adapted to manipulate the printed output. The processor of the device causes the signals to include an initial signal indicating the start of a data transfer and subsequent signals following the initial signal. The signals can be in industry-standard format or a format compatible with the finishing device.
