Copying machines in Donaldsonville are also called copiers or photocopiers, that make paper copies of documents and other visual images quickly and cheaply. They use a technology called xerography, a dry process using heat. They also use other technologies such as ink jet, but xerography is standard for office copying. Xerographic office photocopying has gradually replaced copies made by verifax, photostat, carbon paper, mimeograph machines, and other duplicating machines. Copying machines are widely used in business, education and government sectors in Donaldsonville.
