A barcode printer is a computer peripheral for printing barcode labels or tags that can be attached to, or printed directly on, physical objects. Barcode printers are commonly used to label cartons before shipment, or to label retail items with UPCs or EANs.

A barcode is a code that consists of a series of bars and spaces. Each of these bars and spaces reflect light uniquely. The space reflects lights while the dark bars absorb the light. When the barcode reader starts the scan it uses the light reflected and the light absorbed to read the code.
