Bug 7468 adds a great new feature for printing a batch of barcodes! But part of this process is picking which layout you want to print with. If you select a layout that doesn't include a barcode, you get an error: "Some or all of the barcodes in the range you have selected have no corresponding items. If you are using a layout without barcodes, this may result in missing entries or a blank page" Why not just remove any layouts from the dropdown that do not include a barcode? Even if I enter barcode numbers that are in use, if I try to use this tool to print spine labels for them I get an empty sheet.
