Abstract: According to one embodiment, a tablet printing apparatus includes a conveyor, an inkjet print head, and a controller. The conveyor is configured to convey a tablet having an outer shape that does not determine the printing direction of a print pattern to be printed thereon. The print head includes a plurality of nozzles each configured to eject a liquid to print the print pattern on the tablet being conveyed. The controller is configured to control the print head to perform printing on the tablet being conveyed such that the printing direction of the print pattern is changed at predetermined intervals at least between a first direction which is parallel to or crosses the conveying direction of the tablet, and a second direction which crosses the conveying direction, and in which more nozzles are used for printing than in the first direction.

Abstract: According to one embodiment, a tablet printing apparatus includes a conveying device, an inkjet printing device, and a control device. The conveying device is configured to convey a tablet. The printing device includes a nozzle array in which a plurality of nozzles are arranged in a direction crossing a conveying path where the tablet is conveyed by the conveying device, and performs printing by ejecting ink from the nozzles to the tablet being conveyed by the conveying device. The control device increases either one of a resolution in the conveying direction of the tablet at the time of performing the printing and a resolution in the array direction of the nozzles at the time of performing the printing higher than the other according to a print density or a print shape on the tablet, and controls the printing device to perform the printing.
