A font is a collection of letters, numbers and special characters all
having the same typeface, weight, size, and posture.
Fonts utilised on the 4213 in XES mode are digital fonts — that
is, each character or symbol in the font is a digitised bit map.
Figure 2-4 shows a font character in bit map form. In electronic
form, the printed pixels of the bitmap are represented by ones,
the unprinted pixels, by zeros.
