Set Print Position (absolute)
Description: Moves the printhead to an absolute horizontal position on the paper. The distance is
specified in dots from the left margin to the new print position (at which subsequent
characters are printed). The distance in dots is defined as:
number of dots = n1 + (n2 * 256)
Each dot represents 1/60 of an inch.

If the position specified moves the printhead outside the current margins, the command
is ignored and the previous setting remains in effect. This command is also ignored in
right, center, and full justification modes.
