Greetings, @KDavidson .
Thank you for joining the thread and posting this question!
I understand that you’re looking for a thermal printer that can print both, shipping and barcode, labels wirelessly from your iPad Pro. However, due to the difference in label sizes and wireless printing capabilities, I didn’t have any luck finding one that is suitable for both tasks.
If you’re looking for a wireless thermal printer for Shopify shipping labels, then you can look at the Brother QL-1110NWB. Nevertheless, it’s important to note that if you’re using or planning to use a third-party app for shipping labels (incl. return labels), such as ShipStation or Shippo, then you need to use the DYMO LabelWriter 4XL or a standard desktop printer.

As for the supported DYMO and Zebra printers for barcode labels, you can choose between the DYMO LabelWriter Wireless Label Printer or Zebra Label Printer (Wireless) to use with your tablet.
Since shipping labels can be printed using a standard desktop printer, then you may be able to consider just buying one thermal printer for the barcode labels. That being said, do you have a standard desktop printer? If so, does it support wireless printing with your iPad Pro?
