Unit of Measure Command

The Unit of Measure command establishes the unit of measure for PCL Unit cursor movements.

	? & u # D
	# =Number of units-per-inch
Default	= 300
Range	= 96, 100, 120, 144, 150, 160, 180, 200, 225, 240, 288, 300, 360,
	400, 450, 480, 600, 720, 800, 900, 1200, 1440, 1800, 2400, 3600,
	7200.

The value field defines the number of units-per-inch used in the following commands:

zVertical Cursor Position (PCL Units).

zHorizontal Cursor Position (PCL Units).

zVertical Rectangle Size (PCL Units).

zHorizontal Rectangle Size (PCL Units).

In addition, the current unit of measure setting affects the HMI setting, which in turn determines how cursor movement values are rounded. This affects the result of the following commands:

zHorizontal Cursor Position (Columns).

zHorizontal Tab (HT control code).

zSpace (SP control code).

zBackspace (BS control code).

zBitmap Character Delta X (“Delta X (SI),” Chapter 11).

For example, if the unit of measure is set to 96 (one PCL Unit = 1/96 inch), then the HMI is rounded to the nearest 1/96 inch. If the unit of measure is set to 300 (one PCL Unit = 1/300 inch), the HMI is rounded to the nearest 1/300 inch.

Note	HMI is set either as a result of font selection or through the use of
	the HMI command. The rounding behavior just described only applies
	when the HMI is at its default setting (derived from the currently
	selected font). If the HMI Command was used to override the HMI
	setting, the rounding behavior described above does not apply.
	(See “Horizontal Motion Index (HMI) Command” in Chapter 5 for more
	information.)
