Make a seperate app/ integrate feature in current app, where you can print labels with custom barcode size etc. In a seperate app that would allow you to manage your items / inventory this feature would fit perfectly.
This would be a wonderful addition! It would be extremely useful to us to be able to print labels as shelf price tags. The current labels do not display the price large enough and it would be preferable to be able to include a $ sign in front of the price.
