NCR paper, is also known as carbon-free copy paper or CCP. This carbon-free paper is an alternative to carbon paper, which is used to copy handwritten or original prints without the use of electronic devices.

The advantage of non-carbon copy paper is that they are a free alternative to biodegradable carbon paper and are smudge-free. NCR first produced this product and named it NCR without coal or paper to make it an acronym for their company's national cash register.
