## Abstract

An ink jet recording apparatus which is able to be operated by communication from a higher-level device includes a printing head that ejects ink, a communication unit which is able to perform communicating with the higher-level device, a program storage unit that stores a program, and a printing control unit that controls the printing head, and the program storage unit includes a communication program storage area in which a program corresponding to a predetermined communication protocol is stored in advance, and the program storage unit includes an extension area in which a program corresponding to a communication protocol different from the predetermined communication protocol is installable.

## Claims

### Claim 1

An ink jet recording apparatus which is able to be operated by communication from a higher-level device, comprising:
a printing head that ejects ink;
a communication unit which is able to perform communicating with the higher-level device;
a program storage unit that stores a program; and
a printing control unit that controls the printing head,
wherein the program storage unit includes a communication program storage area in which a program corresponding to a predetermined communication protocol is stored in advance, and
the program storage unit includes an extension area in which a program corresponding to a communication protocol different from the predetermined communication protocol is installable,
wherein the program installed in the extension area is a program having a function of converting, when a setting of a specification in which a setting is unable to be reflected in the ink jet recording apparatus is received from the higher-level device, the received setting to a format of a reflectable specification and reflecting a setting value in software of a main body side of the ink jet recording apparatus, and
the program installed in the extension area and the program stored in advance become mutually executable.

### Claim 2 (depends on 1)

The ink jet recording apparatus according to claim 1, wherein the program installed in the extension area and the program stored in advance become mutually executable.
