FILLING THEN EDGING VS EDGING THEN FILLING When transparency mode ( TR command ) is opaque, filling then edging an object may produce different results than edging and then filling. This is especially true when large pen widths are used. The following example illustrates this. For more information see the PCL 5 Printer Language Technical Reference Manual. NOTE: The following program will draw two circles using different sequences to fill then edge. The circle that is drawn on top is filled then edged, while the circle on the bottom is edged then filled. LEGEND: Ec = [Ctrl] [P] [Esc] in DOS EDIT. EcE Resets the printer.
