You can now have a custom store ID on the order receipts if you have barcodes activated. This is a useful feature for customers that have multiple stores that are scanned in the plant.
In order to set this, you will need to go to Settings > Admin > Plant Mode > General Settings > Custom Store Id for Receipt Barcode:
If this is set, the receipt structure will change from 939900000001 to ID0000000001
*Please note that the first number should not be a 0*
