The Epson LQ-670 / LQ-680 ribbon is a fabric dot-matrix ribbon cartridge designed for impact printing. It uses a high-strength cloth ribbon impregnated with black ink, providing sharp, legible text on plain or multi-part continuous forms. These ribbons have a long print life (up to around 2 million characters per cartridge) and are easy to install with a simple snap-in design. They’re ideal for printing invoices, reports, receipts, labels, and multi-copy documents in business and industrial environments.
