The Epson C13S015339 is a black fabric ribbon cartridge designed specifically for dot-matrix printing. This set comes as a 3-pack, providing you with three separate cartridges to keep your printer running through multiple jobs without interruption. These ribbons are compatible with the PLQ-20, PLQ-20M, and PLQ-22 printer models. Each cartridge is housed in a precision-fit cassette that allows for a quick and easy replacement process. The fabric is engineered to ensure uniform color distribution across the page while preventing fraying, which helps protect the print head from unnecessary damage during operation.
