Hey! Thanks for reaching out about this.

Right now, the ability to customize where things go on bar code labels, like the item name and price, is a feature request. I really see the importance of it, so I have sent it in to our Product team, but for now, we will have to look at workarounds. 

1: The design of each bar code label is sometimes different for each size, so if you have the flexibility to use different bar code label sizes, you can experiment to see if other layouts work best for you. 

2: Some sellers are able to use Avery's templates and print the bar code labels outside of Square: https://www.avery.com/templates. I've heard of other seller's using these templates on Microsoft Word and printing them from Word as well.
