 Specifies the vertical print position as an absolute position from the top margin position.
Vertical position=mL+mH*256+top margin
 The absolute vertical position is measured from the top margin position when this command was specified.
 If a position extending beyond the bottom margin is specified, printing starts.
 There is no restriction on the amount of movement back (upward) from the current position.

(The horizontal position does not move to the left margin.)
With right alignment and center alignment, the horizontal position moves to the beginning of the line.
