Paper rolls can be inserted into compatible printers to produce sheets and documents of various lengths. Wide-format paper rolls offer continuous use when printing banners, posters, and retail displays. Adding machine, point-of-sale, and calculator paper rolls provide printed copies of receipts and calculations in business applications. Thermal paper rolls for thermal printers use heat transfer instead of ink to print receipts and records. Thermal facsimile paper also prints with heat transfer when used in compatible fax machines.
