How can I stop my Brother QL-820NWBc from cutting each barcode label individually?

[NikNik67]

I am trying to stop my Brother QL-820NWBc from auto-cutting my barcode labels after every single one! These are printed from a 3rd party app in Shopify (Easyscan) and not from their P-Touch Editor. The label itself prints perfectly. I am using a roll of die-cut DK-11209 labels....I have turned Auto-Cut off on the printer itself but this doesn't work. I think it has something to do with the fact that the app produces each label as a "pdf", so it sees each label as a separate page. It was never an issue with our old Zebra. Surely you should be able to override this by turning the auto-cut off. It's driving me insane as sometimes I have 200 barcode labels to print. HELP!
