Until not long ago dot matrix printers were among the most popular print technologies on the market. They offered the benefit of low maintenance costs and the unique capability to print on duplicate roll paper and output each document in multiple copies in a single pass.  That type of printers used ribbon cartridges, which were based on the same technology as the consumables used in cash registers and typewriters. The ribbon used in printer cassette is usually made of nylon and can print in black or in colour, such as red. Our product offering still includes a variety of ink ribbon cassettes for dot matrix printers, cash registers and typewriters.
