roll

This continuous, narrow sheet of paper, typically wound tightly around a cardboard core, serves as the medium for printing calculations and records on adding machines. Commonly made of thermal paper, it provides a quick and easy way to document numerical data. A simple example is its use in grocery stores to provide customers with a detailed list of purchased items and the total cost.

Historically, these paper rolls played a crucial role in accounting and bookkeeping, offering a tangible record of transactions before digital systems became widespread. Although electronic calculators and computers have largely replaced adding machines, the medium remains valuable in specific applications. Its enduring utility lies in its affordability, portability, and the immediate, physical record it creates. This tangible format is especially beneficial in environments where electronic devices might be impractical or unreliable.

This continuous-feed paper, typically packaged in rolls, is specifically designed for use in adding machines and certain types of calculators.
