An operator interface is provided whereby an operator can define the size and number of columns across the strip paper. Instead of producing a series of small plots along one edge of the wide strip, the system includes logic to place the series of plots sequentially across the columns of the strip paper before advancing the strip paper to a next writing area. A paper slitter is also provided to slit the paper on the column lines after the printing thereon.
