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.

First claim

What is claimed is:

1. A printing device comprising:
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, at a position where the head and the printing medium face each other.

2. The printing device according to claim 1 , further comprising:
a moving mechanism configured to move the head in one direction relative to the platen,
wherein the controller is configured to cause the head to perform the non-ejection drive in at least a part of the period other than the ejection period, in a case where the head is moving in the one direction.

3. The printing device according to claim 2 ,
wherein the controller is configured to cause the head to perform the non-ejection drive in all of the period other than the ejection period, in the case where the head is moving in the one direction.

4. The printing device according to claim 1 ,
wherein the head includes:
a first head portion including a nozzle configured to eject a first ink; and
a second head portion including a nozzle configured to eject a second ink onto the first ink, the second ink being different from the first ink, and

in a case where the controller is configured to cause one of the first head portion and the second head portion to perform the ejection drive, the controller is configured to cause an other head portion of the first head portion and the second head portion to perform the non-ejection drive.

5. The printing device according to claim 4 , further comprising:
a moving mechanism configured to move the head in one direction relative to the platen,
wherein the first head portion and the second head portion are arranged side by side along an intersecting direction intersecting the one direction.

6. The printing device according to claim 1 , further comprising:
a pretreatment liquid application mechanism configured to apply the pretreatment liquid to the printing medium.

7. The printing device according to claim 6 ,
wherein the controller is configured not to cause the head to perform the non-ejection drive, in a case where the pretreatment liquid is not applied to the printing medium by the pretreatment liquid application mechanism.

8. The printing device according to claim 6 ,
wherein the pretreatment liquid application mechanism is configured to spray, in a mist form, the pretreatment liquid onto the printing medium.

9. The printing device according to claim 1 ,
wherein the pretreatment liquid contains an organic acid, as the volatile component.

10. A non-transitory computer readable storage medium storing a control program used in a printing device including 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,
the control program, when executed by the controller of the printing device, causes the controller 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
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, at a position where the head and the printing medium face each other.
