A low-cost hardware circuit is described which will enable matrix-type printers to plot vector data. The data to be plotted can be precomputed and stored in the printer or can be transmitted from a host computer system. The former is useful for preprinted forms and the latter, for producing engineering drawings or adding illustrations to text-processed prints. The precomputed data supplies the capability for storing forms in a printer and for merging the alphanumeric data to be displayed on the form so that formatted displays can be produced without the need for storing a large number of forms. Graphic data can also be printed in a variety of forms, such as from a CAD/CAM system on the printer. The hardware to be added to a raster-scan printer, such as the IBM Model 6670 Information Distributor, is illustrated in Fig. 1.
