A barcode reader is an optical scanner that can read a printed barcode, decode the data in the barcode, and send the data to a computer. Like a flatbed scanner, it consists of a light source, a lens, and a light sensor that converts optical pulses into electrical signals.
The purpose of a barcode reader is to scan or read a barcode and then provide electrical output to the computer through a set-top box and cable. The decoder recognizes the type of barcode symbiosis it sees, translates the bar and spatial content, and transmits the data to the computer in a human-readable format.
Thermal printing (or direct thermal printing) is a digital printing process that produces a printed image by passing paper with a thermally pigmented coating, commonly referred to as thermal paper, through a printhead made up of elements heated by a small electrode.

Thermal printing works by heating thermal paper, which has a special coating that reacts to heat. It uses a thermal head to focus heat onto the paper in a specific pattern and in doing so, renders text on the paper.
