Explains why the TS2040 printer distorts screen drawings (rectangular vs. square pixel grid) and provides the correction: divide variable x-coordinates by aspect ratio A=0.82 (or multiply variable y-coordinates by 0.82). Eight program examples demonstrate the correction for diagonal squares, circles, and slanted equilateral triangles on both TS1000/1500 (PLOT/DRAW) and TS2068 (DRAW/CIRCLE statements). Editor notes full-size printers may use 0.91 instead.
