Unanswered questions: Which specific thermal printers work with Order Printer? Can third‑party customizations be printed via POS to thermal printers at all?
Which thermal printers are compatible with the Shopify OrderPrinter app? I am yet to find a suitable third party app that is able to print to a thermal receipt printer?
(Example) - Customisations from third party apps cannot be printed on a thermal receipt printer within the Shopify POS app?
