I would like to suggest a feature to create product labels that an user can print.
Ideal situation for me would be like:
1. Create PO
2. When incoming stock arrives at our warehouse, create for each product a label with the product name, barcode, EAN number and some other details like size or something.
3. Then generate a pdf file with the selected format (size of labels) and print them.
4. Now we can label al the ordered products with our own labels for the batch that just arrived.
