command lowers the density of the print—24 dots/mm becomes 12, 12 dots/mm becomes 6, 8 dots/mm becomes 4, and 6 dots/mm becomes 3.
^JM
also affects the field origin (
^FO
) placement on the label (see example below).
Set Dots per Millimeter
When sent to the printer, the
^JM
command doubles the format size of the label. Depending on the printhead, normal dot-per-millimeter capabilities for a Zebra printer are 12 dots/mm (304 dots/inch), 8 dots/mm (203 dots/inch), or 6 dots/mm (153 dots/inch).
This command must be entered before the first
^FS
command in a format. The effects of
^JM
are persistent.

Comments:
If
^JMB
is used, the UPS MaxiCode bar code becomes out of specification.
