HP 5961-0509 manual Cursor Positioning Units, PCL Units

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:

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 how cursor movement values are rounded, in turn affecting 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 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.
