  • Patent number: 12030303
    Abstract: Disclosed is a printing apparatus in which web paper is transported to a printing face contact roller in a swirling form while a direction thereof is turned by first to fourth turning rollers. Heating units are arranged so as to face a printing face of the web paper between the two first and second turning rollers, between the two third and fourth turning rollers, and between the fourth turning roller and the printing face contact roller individually. Such arrangement can achieve a compact drying mechanism. The heating units each directly heat inks on the printing face, and thus do not overheat the web paper. Moreover, the heating units are not directed upward. This avoids contact of the web paper to a front side face of each of the heating units when the web paper slackens.
