Back in the day, most printers used LPT Serial DB25 cables to tether to your computer. Now? You use a simple USB printer cable - also known as a B-type USB cable - to hook up your printer. USB printer cables have two different ends on them - one square that goes into your printer and the other flat to go into your computer. Our USB printer cables here at FireFold are top notch! We provide them in a variety of colors and lengths to ensure that we can meet your needs.
