Abstract
A group of selected character codes is converted into character patterns in advance and stored in a font cache memory, and, when one of the character codes is received as the printing instruction, such pre-converted character pattern is utilized for printing. Thus the conversion into the character pattern can be dispensed with at each code reception, and the time required for such conversion can be shortened.
Claims14
An output control apparatus comprising:
- font data memory means for storing first font data from which a character pattern is generated by a first font scaler and second font data from which a character pattern is generated by a second font scaler;
- character pattern memory means for storing the character pattern generated by the first or second font scaler with information showing by which one of the first and second font scalers the character pattern was generated;
- determining means for determining whether said character pattern memory means stores a character pattern generated by the first font scaler from the first font data corresponding to a pattern to be output;
- and
- output means for, in response to a determination by said determining means that said character pattern memory means stores a character pattern generated by the first font scaler from the first font data corresponding to the pattern to be output, outputting data based on the stored character pattern and, in response to a determination by said determining means that said character pattern memory means does not store the pattern, for generating a character pattern by means of the first font scaler from the first font data corresponding to the pattern to be output and outputting data based on the generated character pattern.
An output control method using a font data memory for storing first font data from which a character pattern is generated by a first font scaler and second font data from which a character pattern is generated by a second font scaler and a character pattern memory for storing the character pattern generated by the first or second font scaler with information showing by which one of the first and second font scalers the character pattern was generated, said method comprising the steps of:
- determining whether the character pattern memory stores a character pattern generated by the first font scaler from the first font data corresponding to a pattern to be output;
- and
- in response to a determination in said determining step that the character pattern memory stores the character pattern generated by the first font scaler from the first font data corresponding to the pattern to be output, outputting data based on the stored character pattern and, in response to a determination in said determining step that the character pattern memory does not store the pattern, generating a character pattern by means of the first font scaler from the first font data corresponding to the pattern to be output and outputting data based on the generated character pattern.
