Abstract
A heating device includes a pre-heater configured to pre-heat a medium, onto which a liquid is discharged from a liquid discharger, at a first position upstream of the liquid discharger in a conveyance direction of the medium, a print-heater configured to heat the medium at a second position opposite the liquid discharger, a post-heater configured to post-heat the medium at a third position downstream of the second position in the conveyance direction, and circuitry configured to control a temperature of each of the pre-heater, the print-heater, and the post-heater. The pre-heater includes a first pre-heater and a second pre-heater disposed closer to the print-heater than the first pre-heater, and the circuitry controls a temperature of the second pre-heater to be between a temperature of the first pre-heater and the temperature of the print-heater.
