HP PCL/PJL reference (PCL 5 Printer Language) - Technical Reference Manual Part II

EN Working with the Character Cell 23-13
The printer implements the following different types of fonts:
z Scalable outline font
z Bitmap font
z HP-GL/2 Stick and Arc font
These are described in more detail in “Using Fonts” later in this
chapter. Figure 23-6 and Figure 23-7 show each type of font in
relation to its character cell.
Note Proportional fonts do not actually have a fixed character “cell.” The
width occupied by each character depends on the character’s shape.
