Abstract
A printer comprises a convey roller for withdrawing continuous paper from a roll of the paper and conveying the paper along a predetermined convey path. The convey roller is rotated at a predetermined peripheral speed and conveys the paper with a first convey force. Four printing portions are provided sequentially along the convey path. Each of the printing portion has a printing head, and a platen roller which is brought into contact with the paper while opposing the printing head and conveys the paper with a second convey force. A sum of second convey forces of the platen rollers is set to be smaller than the first convey force. The platen rollers are rotated at peripheral speeds higher than that of the convey roller, and such that the peripheral speeds thereof are sequentially increased in an order of a platen roller adjacent to the convey roller toward a platen roller separated from the convey roller.
