A method is described which provides printers with all-points addressable (APA) capability, the ability to reproduce multiple sizes of a given font in any direction and orientation without requiring operator intervention or excessive font storage in the printer. The specific problem addressed is to decrease the memory needed for multiple font sizes and orientations by using vector-defined fonts, and to provide the ability to shear characters. The advent of APA (or matrix, or non-engraved) printing technology provides the capability to print any image that can be defined, within the limits of the printing technology resolution. This provides the ability for a printer to support multiple font sizes and multiple character orientations. It also provides the ability to shear characters.
