Device in a matrix printer of goods labels, in particular a balance with label delivery

Abstract

Abstract In a device with a matrix printer for providing data on products, such as the type, quantity and/or price of a product, the print head is provided with punctiform elements across which a printout medium forming the label is moved stepwise. The elements can be activated selectively against the printout medium by means of a control device and present the product data in the form of a machine-readable bar code consisting of bar-shaped printed tracks with a defined bar width and bar spacing. In order to exclude errors resulting from printing by faulty elements, it is proposed to make it possible for all elements to be driven in a zone outside the printing area, in order to print a test bar in a direction perpendicular to the direction of the bars in the bar code, which will enable damaged elements to be detected by an empty line. <IMAGE>
