What is Line Smoothing?
This function suppresses serrated outlines of characters and images which results in high resolution of printed quality. This function comple-
ments the outlines with a more defined colour between the drawing and background colours.

If [Screening] is set to [Dot screen], set the number of dot lines (resolution). 70 lpi and 100 lpi can be selected. 100 lpi makes finer
images.
