Portable terminal and method

Abstract

Provided is a portable terminal capable of efficiently storing untransmitted print object data as print data in a non-volatile storage unit, and restarting printing by the print object data. Included are a storage unit, a remaining battery capacity detection unit, a print data construction unit that constructs the print data in each [print unit size] from a data start position of the print object data and transmits the print data to an image forming device, and a data storage processing unit that performs a data storage process in which the print object data is stored in the storage unit in each [storage unit size] toward the data start position from a data end position of the print object data when a remaining battery capacity is smaller than or equal to a preset reference value during transmission of the print data by the print data construction unit.
