Elias here with Shopify Support. Thank you for reaching out.
I understand you’re looking for an app to print product labels without barcodes. We have a free app called, Retail Barcode Label, which you can use to do exactly that. Our app allows you to toggle the barcodes on or off and you don’t need to have a SKU set up, this allows you to choose the information you want on the labels. If needed, the app can help with creating SKUs as well!
I’ve taken a couple of screenshots of the app from my test store so you can see the options available for the label:
Is this what you were looking for? If you have any other questions on product labels, don’t hesitate to let me know in this thread!
Here is a list of 15 best printing apps for Shopify stores that I found on Avada. All of them do not require a barcode so you can print product names and colors easily and quickly.
I hope it's useful for you!
