End Prologue
Description: This order ends the prologue section of a segment. It is only valid
if the prologue flag bit is on in the Begin Segment Introducer (BSI). When the
BSI prologue flag bit is on, only the following orders are valid before the End
Prologue order:
•
Comment
•
No Operation
•
Segment Characteristics
•
All Set Attribute type orders.

Description: This order is for compatibility with existing products and is a No
Operation order.
71 L1 P1...Pn
Fillet
Description: This order specifies a curved line, which the printer draws
tangential to a specified set of connected, imaginary, straight lines.
The printer joins the points specified in the order by imaginary straight lines.
The printer then fits a curve to the lines. The curve is tangent to the first line at
the start point and is tangent to the last line at its end point. If there are
intermediate lines, the curve is tangent to these lines at their center points.
L1 is a one-byte value that specifies the length of the following parameters. L1
must be a multiple of four and cannot equal zero. If L1 equals four, the printer
does not draw the fillet, but the printer updates the graphics current position to
the point specified by parameters P1 to P4.
Parameters P1 and P2 form a two byte value that specifies the X coordinate of
the first point. Parameters P3 and P4 form a two byte value that specifies the Y
coordinate of the first point. Parameters P5 to Pn, if present, form two byte
values that specify the corresponding coordinate values for additional points. If
only two points are specified, the printer draws a straight line.
The printer uses the current values of color, mix, line type, and line width when
drawing the fillet.
This order updates the current graphics position to the coordinates of the last
point.
