Abstract: In a printer, a controller builds a glyph index table in which no glyph data is registered. When it is determined that no set of glyph data corresponding to a character code selected in print data is registered in the glyph index table, the controller acquires a target set of glyph data from the font information in a memory. The target set of glyph data corresponds to the character code. The controller registers the target set of glyph data in the glyph index table. When it is determined that the set of glyph data corresponding to the character code is registered in the glyph index table, the controller acquires the target set of glyph data from the glyph index table. The controller generates raster data from the print data using the target set of glyph data, and perform a printing process to print an image based on the raster data.
