Unit Of Measure - Brother HL-Series Technical Reference Manual

Coordinates
The printer control language coordinate system has its origin at the intersection of the left edge of the logical page
and the top margin. The x-coordinate value of the current cursor position increases as the cursor moves from left
to right, the y-coordinate value increases as the cursor moves down the page. The cursor can be explicitly
positioned anywhere on the current logical page using the PCL coordinate system. In addition, the cursor's
coordinate position will change as text and graphics are printed.
Units
You can specify cursor movement within the PCL coordinate system using one of three different unit systems.
Decipoints
A decipoint is one-tenth of a typographic point measurement = 1/720".
Rows and columns
Using the horizontal motion index (HMI) (Esc&k#H) and vertical motion index (VMI)(Esc&l#C) commands you
can set the width of a column and the height of a row. You can then use the column width and row height as the
units of the coordinate system. The line-spacing command is an alternative to the VMI command.
Units
A unit is the measurement which can be defined by the unit of measure command.

Unit of Measure

Esc&u#D
• # value can be 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.
• # stands for the unit of measurement in dots per inch.
• The value set by this command is used as the unit setting for use by other setting commands such as ESC*p#X.
• The default value of # is 300.
Example)
Esc&u300D
Esc&u600D
(27)(38)(117)#(68)
Esc*p+100x+200Y
move cursor 100/300 inch right and 200/300 inch down.
Esc*p+100x+200Y
