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.

In example implementations, a printing device is provided. The printing device includes a printer module, a plurality of dryer modules, and a side exit unit. The printer module is to print on a continuous web of print media. The plurality of dryer modules is located downstream from the printer module. The continuous web of print media is fed in a wrap-around direction from an outermost dryer module to a center dryer module. The side exit unit is coupled to the center dryer module to redirect the continuous web of print media along an outer side of the plurality of dryer modules.

A drying device includes a first-heating rotator configured to contact a sheet twice from different directions, and at least three second-heating rotators each configured to contact the sheet once. The at least three second-heating rotators are in a conveyance path configured to guide the sheet to contact the first-heating rotator again after the sheet contacts and passes the first-heating rotator.
