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 creating an order it will check to see if a heat seal ID is applied to that product. Either with an ID in the ID field, or if the New Tag checkbox is checked.

It will not let you place an order if the product has no heat seal attached.
