ZPL Commands 199
^JM
^JM
Set Dots per Millimeter
Description The ^JM 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).
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.
