Client side it should download automatically. 2. Create a Spring Rest controller which receive bill number and fetch bill details from database and directly print should happen. Invoice format should be like attached file. (half of the a4 size paper is the size of a invoice, if there is more items it should continue in next page and it should have same header and footer in next continuation of invoices) For this, You can use dummy data to generate invoice instead of getting it from database.
