The apparatus has program modules for processing quantized image information in accordance with characteristics of an image output apparatus by different methods and virtual switches provided in a program. Prints are produced until the process-control time interval elapses, as measured by a timing device. The platform is pivotable with respect to the support brackets in order to permit the platform to be angled relative to the keyboard for optimum comfort and the base is slidable with respect to the support brackets in order to reduce the footprint of the support when the keyboard is not in use. The grapes of this new variety are produced on strong stems and branches and are well adapted to commercial handling.
