A multifunctional tape printer of tape measure, is provided with a main frame (1), a small number (for foot) roller (3) with the perimeter of 3 feet or/and a small number (for meter) roller (5) with the perimeter of 1 meter mounted on the main frame (1), pinch rollers and rubber brush on the rollers as well as ink supply device and tape conveying devices, which constitute the main body of the tape printer, the tape printer being featured by that an additional functional component of a large number (foot) roller (4) or/and large number (meter) roller (6) are mounted on the main frame (1) for matching with the small number (for foot) roller (3) with the perimeter of 3 feet or/and the small number (for meter) roller (5) with the perimeter of 1 meter, the large number roller(s) is/are kept at the same linear velocity to that of the small number roller(s), moreover, the large number roller and small number roller, through the proportioning of mechanical transmission rotating speed, achieve that when a small number roller rotates for one circle, the corresponding large number roller will rotate for an angle of a large number unit. It can print both large numbers and small numbers mechanically at the same time, which has high efficiency, fine printing precision and low rate of rejects and can reduce labor intensity.
