kinda. the device in your image only does the job of weighing product, and applying a price per weight to the measurement and printing a barcode label based on that. the 4011 will probably only be used by cashiers, who usually have a number pad to enter those numbers into the point of sale system, instead of a button for each possible number. the device in your image is probably designed like that because it’s for customers and easier to operate. there is probably a chart somewhere out of frame that translates those numbers into products.
