We have designed our ribbons for Panasonic printers very carefully and we test them to save you time and money without compromising print quality. Our most advanced technologies combined with the best components have made a product that matches or surpasses the performance of the original ribbon from Panasonic. We pack each ribbon in a plastic bag to protect the product against damage and contamination. Asarto’s ribbons for dot matrix printers are warranted for 24 months. With your benefit in mind, confident in our quality, we will also extend our warranty on your device while you use our consumables. If the device is damaged, we will repair or replace it.
