Hi L,
Sorry about the misunderstanding. We do not currently offer any shipping label printing services, so you will want to continue printing your shipping labels through Paypal or your My eBay page, just as you have done prior to joining Auctiva.
If you have any other questions about your account, please feel free to contact our customer support team using the form on the following page of our site:
