Creating graphics for TV and storage tube displays is common and easy at most computer installations today. It is less easy to produce high-quality hard-copy of graphics for publication. This manual describes a program called Plaster which produces a raster representation of a picture created with the PlotlO graphics package for display on the Santec S700 printer. Plaster (PlotlO to Raster) thus allows one to obtain hard-copy of an image created with the prevalent and easy to use PlotlO language on the inexpensive but high quality Santec printer.
