Media processing apparatus capable of printing label on storage media without interrupting

A method for controlling a media processing apparatus configured to communicate with a control apparatus, the media processing apparatus including a data writing unit that writes first write data and second write data to a medium, the first write data and second write data being received from the control apparatus, and a printing unit that performs printing on a label surface of the medium, the method comprising:

• receiving the first write data from the control apparatus;
• writing the first write data to the medium by the data writing unit;
• receiving the second write data from the control apparatus after the first write data is received;
• writing the second data to the medium by the data writing unit;
• and
• after the second write data is received, receiving, from the control apparatus, a medium close command that commands close processing on the medium,
• terminating write processing by the data writing unit in response to the received medium close command, and
• performing printing on the label surface by the printing unit.

A non-transitory computer-readable storage medium storing a program executed by a controller in a media processing apparatus configured to communicate with a control apparatus, the media processing apparatus including a data writing unit that writes first write data and second write data to a medium, the first write data and second write data being received from the control apparatus, and a printing unit that performs printing on a label surface of the medium, the program instructions comprising:

• receiving the first write data from the control apparatus and causing the data writing unit to write the first write data to the medium;
• receiving the second write data from the control apparatus after the first write data is received and causing the data writing unit to write the second data to the medium;
• and
• receiving a medium close command from the control apparatus after the second write data is received, the medium close command commanding close processing on the medium, terminating write processing by the data writing unit in response to the received medium close command, and causing the printing unit to perform printing on the label surface.
