CONTROL DEVICE, CONTROL METHOD OF A CONTROL DEVICE, AND A STORAGE MEDIUM

摘要

A feature of the recording device is used to shorten the length of time that a wireless communication link with a recording device is not established for a control device that communicates wirelessly with a recording device when a wireless communication link can be established. A communication control unit 15b of a host computer 10 detects and reports to a recording control unit 15a that printer 11 power was turned off. After receiving this report that the printer 11 power is off from the communication control unit 15b, the recording control unit 15a requests the communication control unit 15b to establish a wireless communication link with the printer 11 and open a virtual COM port during the period until a new wireless communication link with the printer 11 is established.
