Hi,
Well, the format for the labels depends on the country / shipping provider and it also depends on what printer you have and what it can do. So providing a screen to print labels is not as easy as it sounds.
So based on your printer, you need to find a software for label printing which works great with it to print the labels you need. Usually, these tools have an import feature where you can provide a CSV of the address data to be used for the printing.
Then, in HikaShop, you can create a mass action on the "order" data, with an action "export CSV file" and select the address columns you want to be in the CSV. Make it a button and save.
Then, on the orders listing, when you have a bunch of orders for which you want to print the labels, you can select the orders and click on the button of the mass action to get the CSV file. Then, import it in your software and print with the adequate label template.
The website avery.com which is famous for selling label paper for printers, actually has a free to use tool on their website to print labels:

It handles any kind of label format, templates, and CSV import. So you can do it with that.
