- Make sure you have the Heat Seal feature enabled in your account from Settings > Printers > Heat Seals
- Go to Settings > Products
- Click on the edit pencil next to the product
- Under 'Slot Space', select your preferred option
33% means it takes up 1/3 of a slot
50% means it takes up 1/2 of a slot
66% means it takes up 2/3 of a slot
100% means it needs its own slot
Note: this option is only available with Metalprogetti.
