ABSTRACT:
A code generated by a keyboard or external data source is first converted to an ordinal number code which is processed by first and second algorithms to generate a typing force index and a character type location identifier respectively. The typing force index is used as a variable in an equation whose solution provides typing force information, and the character location identifier is used to calculate character type location information. The information is utilized to position a selected character on a print wheel and to print the selected character with a force depending on the area of the character.
