In fact, people want a receipt, which should be provided as a merchant. Such a receipt is different from an invoice and does not need to be taxed. Just buy a receipt at the office supplies store, and then issue a receipt according to the customer's requirements and stamp your store.
However, you must be careful not to issue contents that are risky to your business at will according to customers' requirements, because after you stamp it, it means that you will be responsible for the contents you issue, and the contents will be as consistent as possible with the goods you sell. Although there will not be so many villains, you should take precautions against risks in doing business. Besides, Taobao is becoming more and more standardized now, and most buyers should be able to understand and accept unreasonable requirements.
