^MU

^MU

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.

Set Units of Measurement

^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.
Format:
^MUa,b,c

Example:
 This is an example of Setting Units:
Assume 8 dot/millimeter (203 dot/inch) printer.
Field based on dots:
    ^MUd^FO100,100^GB1024,128,128^FS
Field based on millimeters:
    ^MUm^FO12.5,12.5^GB128,16,16^FS
Field based on inches:
^MUi^FO.493,.493^GB5.044,.631,.631^FS
Example:
 This is an example of Converting dpi Values:
^MUd,150,300
Convert a 150 dpi format to a 300 dpi format with a base in dots.
^MUd,150,600
Convert a 150 dpi format to a 600 dpi format with a base in dots.
^MUd,200,600
Convert a 200 dpi format to a 600 dpi format with a base in dots:
To reset the conversion factor to the original format, enter matching values for parameters b and c:
    ^MUd,150,150
    ^MUd,200,200
    ^MUd,300,300
    ^MUd,600,600
Comments:
 This command should appear at the beginning of the label format to be in proper ZPL II format. To turn the conversion off, enter matching values for parameter
b
 and
c
