Abstract
A second printing unit includes a mark detection means for detecting a positioning mark that a first printing unit has formed on a front surface of a web. A control means controls web-transport speed in the second printing unit so that a time difference between a generation timing of a CPF-N signal and a detection timing of the positioning mark becomes constant, and also stores the web-transport speed into a memory. During a subsequent printing operation, a web-transport speed is controlled to be the same as the web-transport speed stored in the memory for a period until a positioning mark is first detected after the printing is started.
