If you want to print multiple barcodes, for all storage places, for example, you may need to check your browser settings.
When you want to print more than one barcode and it displays nothing or just 1 barcode for print:
1. Go to your browser settings, just click on the lock next to the URL and click Site settings to see all of them –
2. You have to allow ‘Ads’ and ‘Pop-ups’. Now you can print multiple barcodes.
