DRAWING BEZIER CURVES The Bezier Absolute ( BZ ) and Bezier Relative ( BR ) commands use your current pen position as the first control point in the bezier curve. You specify the second, third and fourth control points. For more information see the PCL 5 Printer Language Technical Reference Manual. The following example shows a simple command sequence using BZ ( Bezier Absolute ) to draw a Bezier Curve in the shape of a sine wave.
