User-defined Characters
Design grids
To design a character you use a grid that is 24 dots high - one
dot for each nozzle on your printer’s print head. The width of
the character matrix is dependent upon 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 maximum, with the dots fot both Letter Quality
and proportional spaced more closely together than those for
draft.
The illustration below shows two grids for designing normal
height draft characters and proportional characters. The line at
the side labelled cap height indicates the top of a standard
capital letter, and the line labelled 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 used for underlining.
