Set Print Position (relative)

The print head is moved to a horizontal position on the paper, relative to
the current print head position. The distance specified is in dots. To deter-
mine n1 and n2, first calculate the displacement required in 1/120ths of an
inch. If the displacement is to the left, subtract it from 65536. The values
for n1 and n2 determine the distance, as follows:
number of dots = n1 + (n2 * 256)
Maximum displacement is ±960. If the position specified would place the
print head outside the current margins, this function is ignored and the
previous setting remains in effect. This function is also ignored in right,
center, and full justification modes.
