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.
