EN Cursor Positioning Units 6-3
Cursor Positioning Units
Cursor positioning is done in PCL coordinate system units. The units
of the X-axis of the PCL coordinate system may be PCL Units,
decipoints, or columns. The units of the Y-axis of the PCL
coordinate system may be PCL Units, decipoints, or rows.
PCL Units
The current unit size used in PCL Unit moves is determined by the
value specified in the Unit of Measure command, defining the number
of units-per-inch used in the following commands:
z Vertical Cursor Position (PCL Units).
z Horizontal Cursor Position (PCL Units).
z Vertical Rectangle Size (PCL Units).
z Horizontal Rectangle Size (PCL Units).
In addition, the current unit of measure setting affects how cursor
movement values are rounded, in turn affecting the result of the
following commands:
z Horizontal Cursor Position (Columns).
z Horizontal Tab (HT control code).
z Space (SP control code).
z Backspace (BS control code).
z Bitmap Character Delta X (Delta X (SI), Chapter 11).
For more information, refer to the next section, “Horizontal Cursor
Positioning (Columns) Command.”
If no unit of measure value is specified, the default number of
units-per-inch for PCL Unit moves (horizontal and vertical rectangle
size, etc.) is one Unit equals 1/300 inch. This is true even when a
different resolution (such as 600 dpi) is selected on the printer.
