Why Isn't the Label Printing?
When adding a new product to an FBA batch, Amazon may not provide the FNSKU immediately.
AccelerList needs the FNSKU assigned to the listing before it can generate the correct product label.
When Can I Print the Label?
Once the item has successfully synced with Amazon and its FNSKU is available, you can print the product label.
You can also print the required product labels while completing Box Content for your shipment.
What About Replenishment Items?
If you're replenishing an existing FBA listing, its FNSKU already exists. This allows AccelerList to print the existing product label as the replenishment item is added to the batch.
Important
Avoid assuming that your printer is malfunctioning simply because a new item's FNSKU doesn't print immediately. First verify whether the listing has synced and the FNSKU has become available.
