^MU
Set Units of Measurement
Description The ^MU command sets the units of measurement the printer uses. ^MU works
on a field-by-field basis. Once the mode of units is set, it carries over from field to field until a
new mode of units is entered.
^MU also allows for printing at lower resolutions — 600 dpi printers are capable of printing at
300, 200, and 150 dpi; 300 dpi printers are capable of printing at 150 dpi.
