^MU - Mode Units

Overview

The ^MU command sets the printer's units of measurement for field definitions. It works on a field-by-field basis and carries over from field to field until a new mode units command is entered, allowing mixed unit types within a single label format.

Syntax

^MUa

Parameters

• a = Units measurement (required)
  • D = Dots (default)
  • I = Inches
  • M = Millimeters

Description

• Specifies units for coordinates and dimensions
• Applies to all subsequent fields until changed
• Can be mixed within single label format
• Affects field origin (^FO), dimensions (^GB), positions, etc.

Measurement Units

Dots (D)

• Default unit
• Resolution-dependent
• 203 DPI (8 dots/mm): 203 dots/inch
• Most precise control

Inches (I)

• Standard imperial measurement
• Useful for US-based designs
• 4 inches = 812 dots at 203 DPI

Millimeters (M)

• Metric measurement
• Useful for international designs
• 100 mm = 793.7 dots at 203 DPI

Usage Notes

• Setting applies to all subsequent fields
• Each ^MU command changes units for following fields
• Can be mixed within single format
• Coordinates interpreted according to current unit
• Default at format start is dots (D)
