Print your own checks and save 50-80% vs. bank and mail order check prices. VersaInk™ combines the highest output quality with the ability to print bank compliant MICR (Magnetic Ink Character Recognition) checks. Checks must include a MICR bank code line, which are numbers and symbols printed in magnetic ink near the bottom of the check. Magnetic ink is required to conform to banking regulations and federal law Check 21, which regulates processing and magnetic ink requirements for printing checks.
