Image recording device and computer accessible storage storing program therefor

摘要

An image recording device is provided with a first memory which is a volatile memory, a second memory, an input unit through which authentication information is input, an authentication judging unit. The recording unit is controlled to print an image on the printing sheet based on the drive data, which is converted from the image data stored in the first memory or the second memory and is stored in the first memory or the second memory. The drive data or the image data is stored in each of the first memory and the second memory is transmitted therebetween. The image recording device further includes a restricting unit capable of restricting power supply to the converting unit and the first memory in a sleep mode.

主权项

1. An image recording device, comprising:
an image recording unit configured to print an image on a printing sheet; a first memory configured to be a volatile memory; a second memory; a receiving unit configured to receive image data which is externally transmitted, the image data being stored in the second memory, authentication being required in order to execute printing based on the image data; a converting unit configured to convert the image data to drive data used to drive the image recording unit, the drive data being stored in the first memory; an authentication judging unit configured to judge whether authentication is performed; a restricting unit configured to restrict power supply to the converting unit and the first memory at a predetermined timing, wherein when a power supply to the first memory is restricted by the restricting unit, data stored in the first memory is deleted; and a control unit, wherein when the authentication judging unit judges that the authentication is performed after the restricting unit starts restricting the power supply to the converting unit and the first memory, the control unit is configured to: start supplying the power supply to the converting unit and the first memory; control the converting unit to generate the drive data based on the image data stored in the second memory, the drive data being stored in the first memory; and control the image recording unit to print the image on the printing sheet based on the drive data stored in the first memory.
