Coordinate System; Bitmap Fonts; Intellifont Scalable Fonts - HP PCL 5 Reference Manual

Coordinate System

Both bitmap and scalable characters are designed in an area referred
to as a cell or window, and each has its own coordinate system and
set of units.

Bitmap Fonts

Characters of a bitmap font are designed within a rectangular area
referred to as a cell. The bitmap character cell is illustrated in Figure
11-3, Figure 11-6, and Figure 11-7. The physical coordinate system is
defined in terms of the directions of raster scan (X) and paper motion
(Y), as illustrated in the following figure.

Note The LaserJet IID, IIP, 2000, and all LaserJet PCL 5 printers rotate
fonts to match the paper's physical coordinate system.

Intellifont Scalable Fonts

Characters of an Intellifont scalable font are designed within a
rectangular area known as the Agfa Design Window (Figure 11-2).
The units of this coordinate system are .01mm square.
