This sequence specifies the distance from the left margin that
subsequent characters are to be printed, using this formula: total
number of dots =
n1 + (n2 X 256). Each unit equals 1/60th of an
inch. The sequence is ignored and the previous setting remains
effective if the position specified is beyond the right margin.
