User-defined Characters
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, indicates the top of a standard capital letter. The line
labeled base 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.
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.
