A communication device is configured to communicate with an information processing apparatus through a first communication interface using a first protocol, and communicate with an image processing apparatus having the image processing function through a second communication interface using a second protocol which is different from the first protocol. A controller of the communication device is configured to obtain particular information of the image processing apparatus from the image processing apparatus using the second protocol. When receiving a search request from the information processing apparatus, the controller responds to the search request based on the particular information as obtained. When receiving a first execution instruction from the information processing apparatus through the first communication interface using the first protocol, the controller transmits a second execution instruction in accordance with the first execution instruction to the image processing apparatus through the second communication interface using the second protocol.
