I am having the same problem which has just started today. All the shipping labels I have printed over the last year and a half have all printed on the top of the page. Now they are printing on the bottom half the the page. When I flip the half sheet Avery label to print the other end, the flimsy (empty) half must be loaded first which causes printer errors 50% of the time. Hoping Shopify gurus can fix this asap. The test label is still printing on the top half of the sheet but actual labels print on the bottom half. There doesn't seem to be any way to fix this on our end.
