Barcode printing is the process of creating visual representations of data in the form of bars and spaces. These codes can be scanned by barcode scanners to quickly retrieve information about products, such as price and inventory levels. Commonly used in retail, logistics, and manufacturing, barcodes help streamline operations and improve accuracy. There are various types of barcodes, including 1D barcodes and 2D barcodes. 1D barcodes consist of parallel lines, while 2D barcodes, like QR codes, can store more information in a square format. Barcode printing can be done using specialized printers or standard printers with the right software.
