Require Heat Seal for a Product

You can require for specific products to have a heat seal barcode associated when creating an order. 
You will only be able to use this feature if you enable heat seals in your store (from Settings > Printers > Heat Seals).  

Setting-up the heat seal requirement for a product:

1. Go to Settings > Products 
2. Click on 'Add Product' or click on the edit pencil next to an existing product
3. Tick the 'Require' box under 'Require Heat Seal' and click update

When a user clicks on a heat-seal required product, he will immediately be prompted to enter the barcode ID or item notes.
