The invention discloses a computer data processing capacity planning system that utilizes known workload planning information along with hardware andor software configuration information from the actual operating environment to accurately estimate the production system capacity available for use in carrying out one or more processing task. At least one color ink of the yellow, magenta and cyan inks includes a first ink and a second ink which have different hue angles h having therebetween the color range of the normal color of the color ink. A gateway is described to perform novel allocation of time slots on upstream frequency channels to allow frequency hopping. The graphic information preferably is customizable by a user, such as by way of a companion software program, which preferably runs on a PC and is coupled to the system via an interface such as a USB port.
