PRINTER, POS SYSTEM, WIRELESS COMMUNICATION CONTROL METHOD, AND DATA STORAGE MEDIUM

A printer having a physical connection port and a wireless communication module for sending and receiving data by wireless communication, a received data processor controlling the received data, and a printing mechanism for running a printing process is provided, as is a POS system having such a printer, a wireless communication control method, and a computer readable medium carrying a program for implementing the method. A virtual port emulator on a host system receives display output requests from a POS application running on the host, finds data for a wired connection port on a printer of a stand-alone system linked to the virtual port for the display data, and sends the display data with the connection port data through a physical port on the host to a printer of the host system. Data received by the host printer is then allocated by a first received data processor and sent by wireless communication through a wireless communication device of the host to the stand-alone system printer. The wirelessly transmitted data received through a wireless communication device of the stand-alone system is then distributed by a second received data processor to a display of the stand-alone system through a wired connection port. That display then displays the received information, that is, the display data from the POS application.
