New products will be created in GroovePacker during the order import. Depending on the import source the Name, SKU and image are often available. The barcode is often not included so this can be added directly in GroovePacker (either before scanning or at the time of scanning). If there are many new items all of their data can be imported with a CSV import. This will allow special packing data, like instructions that the packer should see when packing a specific item, to be added as well.
Also, if the SKU and Barcode are the same value for all of your items it is possible to have GroovePacker generate the barcode from the SKU during the import - in most cases.
Here's how you can generate Barcodes from SKUs for all selected products.
