INFORMATION PROCESSING DEVICE CONTROL SYSTEM USING PORTABLE TERMINAL, PORTABLE TERMINAL, METHOD FOR CONTROLLING INFORMATION PROCESSING DEVICE, AND CONTROL PROGRAM

摘要

PROBLEM TO BE SOLVED: To select an information processing device nearest from a portable terminal and execute a process without having one printer occupied by one portable terminal.SOLUTION: An information processing device control system according to the present invention comprises a distance detection unit 12 for detecting a printer 200 shortest in distance from a portable POS terminal 100 on the basis of the intensity of a radio wave transmitted by a plurality of printers 200 using a BLE and received by the portable POS terminal 100, and a process execution control unit 14 for indicating to the detected printer 200 using a wireless LAN that a printing process be executed. Due to that, even while print data is transmitted using the wireless LAN from some portable POS terminal 100to a specific printer 200, the other portable POS terminal 100, etc., receives the radio wave using the BLE, it is made possible to detect the nearest printer 200 from among the plurality of printers 200 including the specific printer 200.
