Font Size and Spacing
The font typically defines the character size and line spacing. The typical font is proportional
spaced. That is the spacing between characters varies. This is not always the most desirable
mode of operation. To give the programmer some additional control over character spacing and
line height, the Accutherm Supreme
provides a width and height override command.
The following table converts dots to CPI (Characters Per Inch) points and ¼ points and is useful
in calculating point size settings.
