I spent 3 hours tweaking the code in the Shopify 'Order Printer' app to make orders print on eBay (2 label) Invoice Paper. I've tested it on a couple of computers and printers and it seems to align with the eBay invoice template now.
If anyone wants my template, message me and I'll send it to you.
You wouldn't know how to delete the eBay track code that eBay automatically put in address line one on the labels?
Ebay wont remove this but hoping in Shopify there's a way to code it out or code it so it just removes address line 1 of orders when they come from eBay
