This method relates to printers that have electronics fonts. Electronics fonts are sets of character images stored in Read Only Storage (ROS). The character images are loosely bounded by a rectangular box. When they are stored in ROS, these white spaces are stripped off to allow packing more character images within an allowable memory area. The compressed characters must be decompressed to normal shape prior to copying to the Swath memory (Swath is a block of memory where final- form characters, in their appropriate positions, are copied into). This process of decompression is also called rasterization. A character can be in Emphasis (or Bold) mode when: - one copy is printed at its intended position. - one copy of it is printed to the right of it, offset by one pel (unit of character measurement.
