Abstract
Abstract An output apparatus comprises: a cache memory to temporarily store the bit map pattern data which was developed to the bit map pattern on the basis of character information; an accumulating device to accumulate a plurality of bit map pattern data extracted from the cache memory; a rewriting unit to rewrite the bit map pattern data stored in the cache memory; a print controller to print on the basis of the data accumulated in the accumulating device; a detector to detect an operating state in the print controller; and a control unit to control the data rewriting process in the cache memory and the data clearing process in the accumulating device in accordance with the operating state detected by the detector. Since the rewriting and clearing processes to the cache memory are executed synchronously with the printing operation, even if a paper jam occurred, there is no need to develop to the cache memory.
