ABSTRACT:
A character pattern generating apparatus for use in a dot matrix type serial printer. The apparatus includes a character pattern storage apparatus for storing dot pattern data representative of characters corresponding to print codes. A buffer memory, coupled to the character pattern storage apparatus receives dot pattern data corresponding to selected print codes read out from the character pattern storage apparatus representative of at least one character. A font type adjustment apparatus, coupled to the buffer memory, changes the font type of a character output from the character pattern storage means to the buffer memory from a first font type, stored in the character pattern storage apparatus, to a second font type. A line memory stores dot pattern data for a line to be printed. A print head adjustment apparatus, coupled between the buffer memory and the line memory, outputs the dot pattern data stored in the buffer memory to the line memory in the order in which it is to be printed.
