Update data transmission method, firmware writing system, and update data transmission program

摘要

The time required to send firmware update data to a printer or other peripheral device (13a1, 13a2, 13b-13d) is shortened without changing the communication speed. A server (12b) sequentially reads records of a first format, deletes blocks of consecutive blank data that are contained in the object data in records of the first format and are longer than the management data in a second format, and segments the object data before and after the blanks (S109), connects the object data in records of the first format into units of a certain length, generates management data for the segmented object data and generates management data for the connected object data to produce records of the second format, and sends the update data composed of the records of the second format to the printer 13b. Records of the first format written in ASCII code are binary converted (S104), and binary records in the second format are sent to the printer 13b.
