^JMSet Dots per Millimeter

Not supported by zplkit yet

Sets print density: ^JMA is full density, and ^JMB halves it (8 dots/mm becomes 4, for example), doubling the size of everything on the label, ^FO positions included. Place it before the first ^FS in the format, and the setting stays in effect.
