The dot patterns of characters vary according to the font selected. For
example, in the data processing (DP) font at a line spacing of six lines per
inch (lpi), the dot matrix contains 12 dot rows from the top of one character
line to the top of the next. (See Figure 2–1 and Figure 2–2.) At eight lpi there
are nine dot rows per character line, at nine lpi eight dot rows per character
line, and so on.
