CONTROL DEVICE

摘要

A control device may specify a target transportation pathway to be used for transporting a target print medium, select one type of printing control in accordance with the specified target transportation pathway, and control a print performing unit in accordance with the selected one type of printing control. In each of a first type of printing control and a second type of printing control, when a central image is to be printed, the target print medium is transported by a first transportation amount. In the first type of printing control, when an edge image is to be printed, the target print medium is not transported by a transportation amount greater than the first transportation amount. In the second type of printing control, when the edge image is to be printed, the target print medium is transported by a second transportation amount greater than the first transportation amount.

主权项

1. A control device configured to cause a print performing unit to perform printing,
wherein the print performing unit comprises: a printing head comprising a plurality of nozzles which align along a first direction; a medium transportation unit configured to transport a print medium toward the printing head by using one of plural types of transportation pathways, the plural types of transportation pathways including a first type of transportation pathway that may deform the print medium convexly toward the printing head and a second type of transportation pathway that may deform the print medium concavely toward the printing head; a head driving unit configured to cause the printing head to perform a main-scanning action, the main-scanning action including an action for causing the printing head to discharge an ink toward the print medium while causing the printing head to move along a second direction which is perpendicular to the first direction, the control device comprising: a processor; and a memory storing computer-readable instructions which, when executed by the processor, cause the control device to execute: specifying a type of a target print medium to be used for printing from among plural types of print mediums; specifying a type of a target transportation pathway to be used for transporting the target print medium from among the plural types of transportation pathways; selecting, in accordance with the specified type of the target print medium and the specified type of the target transportation pathway, one type of printing control from among plural types of printing controls including a first type of printing control and a second type of printing control; and controlling the print performing unit in accordance with the selected one type of printing control so as to cause the print performing unit to perform printing of a target image on the target print medium, wherein in each of the first type of printing control and the second type of printing control, the medium transportation unit sequentially transports a plurality of times, from an upstream side to a downstream side along the first direction, the target print medium which has been transported along the target transportation pathway, and the head driving unit causes the printing head to perform the main-scanning action each time the target print medium is transported, in each of the first type of printing control and the second type of printing control, when a central image among the target image is to be printed on a central area which is located at a central portion along the first direction on the target print medium, the medium transportation unit sequentially transports the target print medium more than once by a first transportation amount, in the first type of printing control, when an edge image among the target image is to be printed on an edge area which is located at an edge portion along the first direction on the target print medium, the medium transportation unit does not transport the target print medium by a transportation amount which is greater than the first transportation amount, and in the second type of printing control, when the edge image among the target image is to be printed on the edge area on the target print medium, the medium transportation unit transports the target print medium by a second transportation amount which is greater than the first transportation amount.
