ABSTRACT:
A method and apparatus for enabling a printing device to print character data in either a portrait orientation mode or a landscape orientation mode is disclosed. Font data representing a character in a first orientation is stored in a font memory. Translated font data is generated that represents the translated top portion and bottom portion of the character. The data representing the translated top portion is stored adjacent to the original font data, while the data representing the translated bottom portion is stored in a separate area of the memory. In order to maintain a common addressing scheme for both translated and non-translated fonts, the translated and non-translated font data representing the lower portion of the character are interchanged prior to a printing operation when the printing mode is switched.
