You can import label print list in Hike. This feature is useful for you when creating labels for 100s of products in one list and/or labels for a same list of products are printed on regular basis. This feature is available on Hike Plus subscription plans.
You can also use manual product selection and CSV import simultaneously. If a same product is available in both, quantity selection will get summed up. E.g.: if a product that exists in your import list with quantity 5 is also selected in manual product search with quantity 10, Hike will print 15 labels for this product.
