  • Publication number: 20220242129
    Abstract: A printer includes a carriage including a first head and a second head at least partially overlapping in a sub-scanning direction, a first wiper for wiping the first head, and a second wiper for wiping the second head. The printer moves the first wiper to a first contact position where the first wiper is configured to contact the first head, and moves the second wiper to a second non-contact position where the second wiper is not configured to contact the second head. After moving the first wiper and the second wiper, the printer relatively moves the carriage to cause the first head to pass the first wiper at the first contact position.

  • Patent number: 11388048
    Abstract: Visibility of relevance of detailed configurations is improved while deterioration of the visibility of a general configuration between nodes is suppressed. A node coordinate calculation process calculates, upon calculation of deployment coordinates of each node, a degree of importance of an infrastructure resource and a degree of importance of an application, and weights the distance between the application node and the infrastructure node with the reciprocal of the degree of importance of the infrastructure node. Then, the node coordinate calculation process determines deployment of the application node such that the application node is deployed in the proximity of a comparatively important infrastructure node, and determines deployment of the application node on the basis of the degrees of importance of the applications such that a comparatively important application is deployed closely to the infrastructure node.
