Hi Golan, The Shopify barcode printing app doesn't currently support adding the "compare at price" to the label. However, you can use the Dymo software included with your Dymo LabelWriter to customize the type of labels you want to print. Unfortunately this does require additional manual work to get going. We've made note of this as a potential enhancement for a future version of our barocde printing app. Hope this helps.
Why has no one made this a priority? i i know that Shopify is focused mainly on e-commerce, but most of us also have brick and mortar locations with physical inventory on display for live customers. We need to print labels that show both the original price and the sale price when that inventory goes on sale. it isn't enough to have them only online. could we please get this problem solved?
