Abstract: A platen is configured to define a contact surface which is a medium placement surface when being mounted on a printer. The platen includes: first and second members having first and second surfaces, respectively. The first member includes a plate having the first surface. A state of the platen is switchable between: a first state in which the contact surface is formed inside an outer edge of the plate by the first and second surfaces to have a first area; and a second state in which the contact surface is formed by the first surface to have a second area smaller than the first area. In the second state, the first surface forms the contact surface inside the outer edge and the second surface does not form the contact surface.

Abstract: A printing device includes a head including a nozzle configured to ejects ink, a platen including a support surface configured to support a printing medium to which a pretreatment liquid is applied, the pretreatment liquid containing a volatile component that reacts with the ink, and a humidified air supply port configured to supply humidified air to the support surface of the platen that supports the printing medium, the humidified air supply port being provided around the platen in which the support surface of the platen is disposed at a printing position facing the nozzle.

Abstract: A printing device includes a head including a nozzle configured to eject ink, a platen configured to support a printing medium to which a pretreatment liquid is applied, the pretreatment liquid containing a volatile component that reacts with the ink, and a controller configured to cause the head to perform an ejection drive that causes the nozzle to eject the ink and a non-ejection drive that causes the nozzle not to eject the ink, and cause the head to perform the non-ejection drive in at least a part of a period other than an ejection period in which the head performs the ejection drive to cause the nozzle to eject the ink toward the printing medium, in a case where the head and the printing medium face each other.

Abstract: A processor of a printer determines whether execution of wet-on-wet printing, which is printing wet-on-wet with ink onto a print medium to which a pretreatment agent has been applied by a pretreatment portion applying the pretreatment agent to the print medium, is able to be completed. The processor performs first processing of printing by discharging ink from a print head onto the pretreatment agent that has been applied to the print medium, when it has been determined that execution of the wet-on-wet printing is able to be completed. The processor performs second processing differing from the first processing, when it has been determined that execution of the wet-on-wet printing is unable to be completed.

Abstract: The pretreatment agent is a pretreatment agent to be applied to fabric before application of an ink in formation of an image on the fabric and contains a water-based polymer virtually containing no carboxyl group and a crosslinking agent that is crosslinkable with a carboxyl group in a component contained in the ink.
