Design grids
To design a character you use a grid that is 24 dots high—one dot for
each pin on the printer’s print head. The width of the character
matrix depends on the character set in use. For draft characters, the
grid is nine dots wide, for Letter Quality it is 29 dots wide, and for
proportional characters it is 37 dots wide. The dots for both Letter
Quality and proportional characters are spaced more closely
together than those for draft characters.
The illustrations below show the two design grids. The line at the
side, labeled cap height, indicates the top of a standard capital letter.
The line labeled baseline indicates the baseline for all letters except
those with descenders (the bottom parts of such letters as j and y).
The bottom row is usually left blank because it is needed for
underlining.

Letter quality / Proportional
The grid on the right side can be used for either Letter Quality or
proportional characters. For Letter Quality you do not use all the
columns.
