This sequence specifies the distance from the left margin that
subsequent characters are to be printed, using this formula: total
number of dots = nl + (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.

Determines the position (relative to the current position) at which
printing of following data will start. To find nl and n.2, first
calculate the displacement required in dots. If the displacement is
to the left, subtract it from 65536. Send the resulting number
using this formula: total number of dots = nl + (256 X n2).
The command is ignored if it would move the print position
outside the current margins. A unit is 1/120th of an inch in draft,
and 1/180th of an inch in Letter Quality or proportional.
