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.
     
          Note:  The Bezier command is not
                 supported on printers prior to
                 the LaserJet 4 printer.
