    摘要: A thermal printer for forming an image on a sheet, with the image having a plurality of line image data. The thermal printer includes a thermal head having a plurality of linearly arranged thermal elements for forming the image. The total number of the thermal elements to be driven is determined. The thermal elements are driven for a predetermined time period in accordance with the line image data if the number of thermal elements to be driven is not greater than a predetermined value. If the total number of the thermal elements to be driven is greater than the predetermined value, then the predetermined time period is divided into a number of fractional time periods and the thermal elements are intermittently driven for each of the fractional time periods. The predetermined value is determined to avoid sticking between the thermal head and a thermosensitive sheet due to excess heat.

    摘要: 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.

    摘要: A thermal printer for forming an image on a sheet includes a thermal head having a plurality of linearly arranged thermal elements. A number of thermal elements to be driven to form a line image is determined. A time period that the thermal elements are to be driven to form the current line image is then calculated in accordance with a number of thermal elements driven to form a previous line image and the number of thermal elements determined to be driven to form the current line image. The thermal elements are then driven for the calculated time period to form the current line image.

    摘要: A mode control system is provided for a printer having an internal battery. The mode control system selects at least a charge operation for charging the battery and a printing operation for printing an image on a recording sheet fed into the printer. The mode control system also includes a manually operable member. A duration of an operation of the manually operable member is detected, and one of the charge operation and the print operation is selected in accordance with the duration of the operation of the manually operable member.
