SOLUTION: A part corresponding to a sale price area is divided to five keys K1-K5 at a lower stage part of a screen center of a display part formed to an operation part of a label printer with a weighing device attached thereto. When the sale price area is default selected and the key part is reverse displayed, if a weighing flag of the selected sale price area is '0', a 'content', a 'unit character' are displayed on a line displaying a commodity number on the screen, and respective set data '1' and 'sheet' are displayed under the line. When any of the sale price areas receives a key touch, data corresponding to the sale price area of commodities data are displayed to change data, and a bar code provided with a sale price section code is printed to a label.
