What is the difference between a laser scanner and image scanner?

The laser scanner can only read linear barcodes such as UPC’s by reading the reflected light from the barcode. The laser scanner is the most common and cost-effective scanner with a good scan range. The 2D barcodes are too complex for horizontal sweeping, therefore they require an image capture coupled with algorithm software which enables the camera to read the code.
