Abstract
Abstract Characters to be printed by a multiple font printing apparatus are represented by discrete numbers, and the printable characters on the apparatus are represented by corresponding numbers. There is a particular indication associated with each font and this indication is added to the printable character number. In order to print characters from particular fonts, means are provided for modifying the input data representing the desired character with said particular indication.
