Set Print Position (relative)

The print head is moved to a horizontal position on the paper, relative to

the c urrent 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.
