Disclosed is a printing device including: a print head; a camera that photographs a printing target which is printed by the print head; and at least one processor that determines whether or not printing is properly performed to the printing target based on a printed image which is photographed by the camera, and that changes a printing setting by the print head in response to determination that the printing is not properly performed to the printing target.

The present invention relates to the technical field of printer consumables, and particularly relates to a consumable chip, a consumable and a consumable communication method. The consumable chip directly executes a read request without verifying an imaging device check code in the read request of an imaging device, and then, the consumable chip can respond to the read request of the imaging device in time without being limited by an authentication mechanism of the imaging device, thereby increasing the response speed of the consumable chip to the read request of the imaging device, expanding the compatibility of the consumable chip for imaging devices of different types, and obtaining a certain fault-tolerant capability.

A service printer includes a printer printing unit that executes a print function, a scanning unit that executes a scan function, a printer communication unit that acquires, from a service providing server that provides a delivery service of delivering ink, status information indicating at least one of the status of a contract for use of the delivery service and the status of payment of the usage fee for the delivery service, and a printer controller that enables or disables execution of the print function and execution of the scan function based on at least one of the contract status and the payment status that are indicated by the status information acquired by the printer communication unit.

According to one embodiment, an information management system includes a storage device and a control unit. The storage device is provided in a management server communicatively connected to an image forming apparatus to which a cartridge having a consumable item is detachably attached, via a network, and stores information on the consumable item or the cartridge. The control unit limits a predetermined function related to image formation of the image forming apparatus when, based on identification information indicating the cartridge stored in a cartridge storage device provided in the cartridge attached to the image forming apparatus, information on the consumable item or the cartridge is acquired from the storage device, and the acquired information satisfies a predetermined condition indicating that the cartridge is not a genuine cartridge.

A communication system performs wireless communication using electromagnetic field coupling between a transmission coupler and a reception coupler and moves at least one of the transmission coupler and the reception coupler so as to change the position in a predetermined direction of the reception coupler relative to the transmission coupler. In the communication system, the greater the distance between an overlap portion where the transmission coupler and the reception coupler overlap as viewed from a vertical direction to the predetermined direction and an input end of the transmission coupler is, the higher the degree of coupling between the transmission coupler and the reception coupler becomes.

A printing apparatus includes: a mount portion that removably supports a cassette configured to contain a printing medium and including a cassette storage; a printing device configured to draw the printing medium from the cassette and perform printing on the printing medium; and a controller. The controller performs: when the printing apparatus is in a required state in which medium information stored in the cassette storage of the cassette mounted on the mount portion is required, executing obtaining-communication for obtaining the medium information from the cassette, each time when a first cycle has elapsed; and when the printing apparatus is in a non-required state in which the medium information stored in the cassette storage of the cassette mounted on the mount portion is not required, inhibiting execution of the obtaining-communication or executing the obtaining-communication each time when a second cycle greater than the first cycle has elapsed.
