Marking and coding equipment and systems are available for sale in Cartersville. A coding system uses a series of images or prints to signify information. One of the most visible coding systems is the bar code, which can be printed using a coding equipment, such as a hi-resolution barcode and graphics printing system. Marking can also be for putting information on the product or its packaging. The printers used have to be accurate, efficient and reliable. The printing equipment used varies with the dimensions of the print to be generated, and can be either a thermal or a laser printer. Both small handheld systems and larger printers are available in Cartersville. They are manufactured by a number of different companies.
