ABSTRACT:
A dot printer comprises a printing head, a memory, a first MPU for storing the dot-image data, corresponding to the input printing data, in the memory, and a second MPU for reading out the dot-image data from the memory, and supplying this data to the printing head, and for driving the printing head so as to effect a printing operation on the basis of the readout dot-image data. The dot printer additionally has first and second buffers, and its memory is connected to the first and second MPUs, via the first and second buffers, respectively.
