ABSTRACT:
A thermal printer that forms an image on a sheet. The thermal printer includes a thermal head having a plurality of linearly arranged thermal elements, a device for converting image information into bit-map image data, and a device for storing the bit-map image data. A predetermined portion of the stored bit-map image data is transmitted to the thermal head, and a remaining amount of the stored bit-map image data which has not been transmitted to the thermal head is detected. A time interval between a transmission of the predetermined portion of the stored bit-map image data and a subsequent transmission of the predetermined portion of the stored bit-map image data is set, in response to the detected remaining amount of the stored bit-map image data.
